Molality

Molality Molality The concept of molality arises while studying solutions. Molality is also called as molal concentration. A solution is formed when a solute is dissolved in a solvent. Solute is a substance which is dissolved in another substance during the formation of a solution. Solute are usually in smaller quantities. The solvent is a substance which dissolves solute in itself during the formation of the solution. The solvent is usually in larger quantities when compared to the solute. For example, salt is dissolved in water here salt is the solute and water is the solvent. Sugar dissolve in juice, here sugar is the solute and juice is the solvent. Hence when a solute dissolves in a solvent a solution is formed. The solutions in which the solute is evenly distributed throughout the solvent is called as a homogeneous solution. The amount of solute dissolved in the solvents, and the solution formed can all be expressed in terms of concentrations. There are different ways in which the concentration is estimated such as molarity, molality, formality, percent composition and many more. Molality definition: The amount of solute dissolved in one kilogram of the solvent is defined as the molality of the solution. The amount of solute is expressed in moles. Therefore the molal concentration of a solution is the moles of solute in kilogram of the solvent. To find the Molality the required information is Moles of the solute used to form a solution. Amount of the solvent expressed in kilograms. Hence the formula for Molality can be expressed as follows: Units and symbol: The molality of a solution is expressed as m. The units for expressing the molality equals moles/kilograms or mol/kg. Question: Find the molality of 5 moles of Nacl mixed in 2000 grams for the solvent? Here the moles of the solute = 5 moles. The amount of the solvent = 2000 grams. Expressing the solvent in Kilograms = 2000/1000 = 2Kg. Hence using the formula for calculating Molality gives: Simplifying the calculation, Molality = 2.5 m. Question: Find the number or moles of FeO dissolved in 1.5 kg of solvent, if the molality of the solution if 0.3m. Here, the amount of the solvent = 1.5 Kg. Molality of the solvent used = 0.3 m. Hence rearranging the Molality formula for calculating the moles of the solute: This gives Moles of solute = 0.3 x 1.5 = 4.5 moles of Feo. Question: Find the amount of the solvent if 0.24 moles of the solute is dissolved to obtain a molality of 0.48m? Here, the number of moles of the solute = 0.24. The molality of the solution = 0.48 m. Hence rearranging the molality formula for calculating the mass of the solvent gives: The amount of the solvent = 1/2Kg = 0.5 Kg. Finding the moles of the solute: In a few questions the amount of the solute is given, in such cases the moles of the solute need to be calculated before using the molality formula. Here is how the moles of the solute can be calculated: Question: Calculate the molality when 20 grams of KCl is dissolved in 400 gm of the solvent? Mass of solute = 20 grams. Molar mass or molecular weight of KCl = Atomic mass unit of (K + Cl) = 39.0983 + 35.453 = 74.5513 g/mol = 74.6 g/mol (approx.) Moles of KCl = 20/74.6 = 0.27 moles. Amount of solvent in Kg = 400/1000 = 0.4 Kg. Using the molality formula: Therefore, molality of the given solution = 0.27/0.4 = 0.675 m Question: What is the molality of the solution when 15 grams of Na2CO3 is dissolved in a 0.25 kg of solvent to form a solution? Given is the mass of Sodium Carbonate = 15 grams. The number of moles of Na2CO3 is required for finding the molality of the solution. The Molar mass of Sodium Carbonate Na2CO3 = 2 (Na) + C + 3 (O). Refer the periodic table for the atomic mass unit for Na, C and O. Molar mass of Na2CO3 = 2 (22.989770) + 12.0107 + 3 (15.9994) = 105.98844 g/mol = 106 g/mol (approx.) Moles of Sodium Carbonate Na2CO3 = 15/106 = 0.14 Using the Molality formula Hence the molality = 0.14/0.25 = 0.56 m Difference between Molarity and Molality: Molarity and molality are both used to express the concentrations of a given solution. Molarity is the number of moles of solute dissolved in one liter of the solution. Molarity is also called as the molar concentration of the solution. Molarity of a substance gives the concentration with respect to the total solution whereas the molality gives the concentration with respect to the amount of solvent. The units for expressing molarity is mol/L or M. The formula used to calculate the Molarity of a solution is: Another very useful measuring unit used while solving questions related to concentrations is density. Density of a given solution is mass of the substance per unit volume. The units for expressing density are g/ml. The formula for calculating density is: Following are very unique and useful solved examples involving molality and molarity. Question: The molality of a solution formed by dissolving NaCl in a solvent is 0.56m. The density of the solution is 1.8g/ml. What is the molar concentration of the solution formed? The molality of the solution = 0.56m. This implies 0.56 moles of a solute NaCl is dissolved in 1 kg of the solvent. Moles of NaCl = 0.56; Molar mass of NaCl = Atomic weight of (Na + Cl) = (22.989770 + 34.453) = 58.44277 g/mol = 58.44g/mol (approx.) Using the moles formula, mass of NaCl dissolved = 0.56 x 58.44 = 32.73 gm (approx.) Mass of solution = Mass of Solute + Mass of Solvent = 32.73 grams + 1000 grams = 1032.73 grams Density of the solution given = 1.8g/ml. Using the density formula . Volume of the solution = 1.8 x 1032.73 = 1858.91 ml = 1.85891 L = 1.86 L (approx.). Using the molarity formula: Therefore, Molarity of the solution = 0.56/1.86 = 0.30 M Question: The molality of a solution formed by dissolving KI in a solvent is 1.2m. The density of the solution is 2.5 g/ml. What is the molar concentration of the solution formed? The molality of the solution = 1.2m. This implies 1.2 moles of a solute KI is dissolved in 1 kg of the solvent. Moles of KI = 1.2; Molar mass of KI = Atomic weight of (K + I) = (39.0983 + 126.90447) = 166.00277 g/mol = 166.00g/mol (approx.) Using the moles formula, mass of KI dissolved = 1.2 x 166.00 = 199.20 gm Mass of solution = Mass of Solute + Mass of Solvent = 199.20 grams + 1000 grams = 1199.20 grams Density of the solution given = 2.5g/ml. Using the density formula . Volume of the solution = 2.5 x 1199.20 = 2998 ml = 2.998 L. Using the molarity formula: Therefore, Molarity of the solution = 1.2/2.998 = 0.40 M

ACT

How Can Homeschooled Students Prep for the SAT/ACT Students in a variety of academic situations spend months stressing about the SAT and ACT. No matter how prepared you are, you may still feel overwhelmed. After all, either one of these tests can lead you to your dream college or career path. Luckily, some solid preparation can help ease your anxiety and ensure a great scorewhether youre homeschooled or not. Here are a few ways homeschooled students can prep for the SAT or ACT. Build SAT/ACT test prep into your curriculum Homeschooling offers great flexibility, which is one of the reasons many students choose homeschooling. For example, a fantastic way to prepare for either test while in a homeschool program is to build SAT or ACT test prep into your curriculum. You can easily integrate topics that will be present on the SAT or ACT into your normal schedule and lessons, as both the ACT and SAT follow core curriculum standards. Buy or download an ACT/SAT prep book Many homeschooled learners are used to self-paced learning tools and lessons. For this reason, an ACT or SAT prep book may be a great option for you. There are a variety of prep books available, and prices can vary wildly. (You can also download Varsity Tutors free ACT eBook!) Prep books often provide overviews of specific subjects covered on the test, as well as test questions (and even an ACT or SAT practice test). However, this method may not work for everyonea prep book is ideal for disciplined students who are great self-motivators. If this doesnt describe you, you may want to consider other forms of ACT or SAT prep. Take older ACT or SAT tests While test prep books can be useful, the best preparation often comes from taking older versions of the test. By reviewing old exams, you get a feel for the timing, the language of the test, and the types of questions that may be asked. You can purchase older versions of ACT or SAT tests, but you can also find a slew of practice tests and other learning tools online. Practice taking old exams in a simulated testing environment as often as you can. [RELATED: How is the New SAT Scored?] Hire an SAT or ACT tutor Many students in traditional schools hire a tutor to ensure that theyre completely prepared to take a college entrance exam. Homeschooled students also have this option, and many benefit from the tutoring experience. SAT and ACT tutors can help direct your study in productive ways, identifying weaknesses and strengths, and then helping you develop solutions to address those weaknesses. A tutor who is also an expert in the ACT or SAT is especially useful; he or she can offer invaluable advice and services that you may not otherwise learn about. You can score highly on both the SAT or ACT with a little planning and time management. Your homeschool education does not put you any further behind your peers in a traditional schooling environment, but it may affect what study methods work best for you. Experiment with your test prep options, and set high expectations for test day.

This  false cognate  is often misused by Italian beginners.  The correct word for parents is:  i genitori. And a more casual way to refer to your parents is i miei. Now that you know the words for family members in Italian, lets go over how to discuss your family in conversation. A common question when learning about someone’s family is who’s the oldest and who’s the youngest. Below are some useful Italian phrases  to correctly answer this question: maggiore or più grande (the oldest) minore or più piccolo (the youngest) di mezzo (the middle) If you ever need to describe your marital status, you can use the following terms: sposato/a (married) nubile  (single) dicorziato/a (divorced) separato/a (separated) vedovo/a (widowed) SEE ALSO: How to Learn the Italian Alphabet Grammar Tips for Describing the Family in Italian When having a  conversation about your family, there are some important grammar tips you must keep in mind. When referring to a single member of the family, dont use the definite article. For instance,  tua sorella is correct, and  la tua sorella is incorrect.  If there is more than one member, you should use the definite article as you would normally. For example,  le tue sorelle. This rule, however, becomes null if the single family member you are referring to is modified in some way (for example, with an adjective, a prefix, suffix, or if the possessive is loro). In these cases, use the definite article. Here are some examples: il mio caro cugino (cugino is modified by the adjective caro) la mia bisnonna (nonna is modified with the prefix â€"bis) il mio fratellino (fratello is modified with the suffix -ino) la loro sorella (sorella is used with the possessive loro) In addition, when using terms such as mamma and papà, if you use the article (i.e. la mia mamma / il mio papa) it has a more affectionate meaning. If you use it without the article (mia mamma / mio papà) it simply expresses the relationship as your mother or father.

5 Tips from an Elite ACT Tutor

5 Tips from an Elite ACT Tutor ACT SAT Prep and College Admissions Blog So you're getting ready to take the ACT! That's great! Good luck! Here are 5 tips to help you do your best on ACT exam day: Tip #1 Be confident, yet just a tiny bit paranoid. That slight edge of paranoia will help you not to underestimate the ACT. The ACT has 4 sections: English, Math, Reading, and Science, plus an optional written essay component. You've been studying English, math, reading, science, and writing for years and years, so you should be well prepared, right? Well, yes and no. Your background knowledge in each subject is very important and will help you on the test. However, the test makers will often try to lull you into a sense of false security. To do so, over the years the makers of the ACT have developed some rather slippery tricks to try to get you to make mistakes even on topics you're very familiar with. Which leads us to the next tip. Tip #2 Get very familiar with the test format well in advance of test day. Take a practice test. Take two! The more the better. As you take each practice test, you'll familiarize yourself more and more deeply with how the ACT approaches each of the 4 main sections. Work to find your personal best approach for each individual section. An approach that works well for one section may be disaster for another. For instance, you may find that reading the passage before the questions works very well for the Reading section, but slows you down way too much in the Science section. Each section has its own quirks, its own set of common traps and misdirections that try to lead you astray from the right answers, bog you down in unnecessary work, and slow you down. Learn how to spot these common pitfalls and avoid them, and your accuracy rate and pacing should improve substantially. Tip #3 Get to know your calculator and its abilities. The makers of the ACT state that the problems on the Math section can be solved without a calculator. That's true, but remember that many of the problems can be solved much more easily with a calculator, especially a graphing calculator. Make sure that your calculator is a model approved for use on the ACT and that it has fresh batteries. Keep in mind that part of knowing the abilities of your calculator is being able to recognize when it is not the fastest means of finding a solution. Sometimes a quick sketch or simple process of elimination can get you to the right answer faster. Tip #4 Learn how to conserve your energy. When you take the ACT, you'll be at the test center more than 4 hours, including breaks. Don't do more than necessary to answer each question. Lots of practice will enable you to tune out distractions and unimportant information so that you can focus on the material that's most relevant. If you're working on a math problem, remember that you don't have to show every step of your work like you would in school. When practicing for English, try to streamline and simplify the rules of grammar and punctuation so that you can apply them quickly and directly. Tip #5 Use all of the resources available to you. Practice ACT questions and tests are available at the official ACT website. To get even more practice and preparation, there are many other resources available. Schools often provide practice materials. You can search at your local library or bookstore, or online, to find books, flashcards, software, and apps for additional ACT practice. Another important resource you may want to use is a tutor. Individualized, one-to-one tutoring can help you approach your full potential on the ACT. hbspt.cta._relativeUrls=true;hbspt.cta.load(215486, '6baac2ae-05a3-4610-9d1f-265c8cbd809f', {});

3 Top Comedians to Follow as a College Student

3 Top Comedians to Follow as a College Student pixabay.com   And then there are good old comedians people who rely on their own sense of humor to get a chuckle, a snicker, or even a full-on belly laugh out of their audience. If you’re in the mood to be entertained, check out the following list of top comedians you should keep up with. Louis CK One of the most well-known comedians out there now, Louis CK began his career in the 1990s and early 2000s writing for comedians including David Letterman, Conan O’Brien, Dana Carvey, and Chris Rock. He’s frequently performed stand-up on shows such as “Lopez Tonight,” “The Tonight Show with Jay Leno,” and “Jimmy Kimmel Live!” Now, he even has his own official Netflix site, where you can watch his stand-up comedy special that was released on April 4 of this year. Directed by and starring himself, the movie is “witty” and “irreverent” according to the Netflix site, where Louis CK “muses on religion, eternal love, giving dogs drugs, email fights, teachers, and more in a live performance from Washington, D.C.” With a unique, cutting sense of humor, Louis CK’s stand-up is bound to elicit some raised eyebrows and a lot of guilty (or not guilty) laughter. If you enjoy this sort of sharp, witty humor, definitely check out some of Louis CK’s material when you need a break. You certainly won’t regret it. Kevin Hart A comedian who began his career in 2001, Kevin Hart mainly deals with topics on African Americans, racism, American culture, parenting, and self-deprecation, just to name a few. His career really took off starting in 2006, when he released his first stand-up album, I’m A Little Grown Man, and then a second album entitled Seriously Funny four years later. In 2011, his album  Laugh at My Pain  was especially successful and dealt with his personal life experiences. As someone who previously didn’t know much about Kevin Hart or watch much stand-up comedy in general, I found myself laughing uncontrollably after just a few minutes of listening to one of Hart’s many comedy routines about family. No matter what type of comedy you’re into, you’ll most likely find something (or many things) to laugh about while watching Hart perform. You can turn to him for comic relief when you desperately need a break from the monotony of everyday life. Stephen Colbert A bit different from the other comedians mentioned above, Stephen Colbert primarily performs deadpan comedy on subjects such as American politics and culture. Since 2015, he has hosted The Late Show with Stephen Colbert, a late-night TV talk show on CBS. If you’re interested in politics or at least enjoy finding the humor in politics, Colbert may be a good choice for you. Especially with many college students becoming increasingly involved in and educated about American politics, Colbert’s subject matter is bound to provide a fresh new perspective for people to chuckle at. Plus, if you appreciate dry humor, Colbert is a great option to go with. In the midst of everyday stress, having a few high-quality comedians to watch can be a bright spot in your day. Even if it’s just for 10 minutes here and there, you can find something to laugh and smile about to temporarily lift your mood. Just make sure to curb the amount of time you spend watching these comedians, so as not to get too addicted … and you’ll be good.
