Molarity vs. osmolarity | Lab values and concentrations | Health & Medicine | Khan Academy
 
11:32
Molarity and osmolarity may sound similar, but they are two distinct concepts. Molarity (M) is the number of moles of solute per liter of solution. The unit of molarity is the mole (mol). Osmolarity (Osm/L) is the total concentration of all solutes in the solution. The unit of osmolarity is the osmol (osm). Osmolarity can be used to predict whether water will move from one side of a semipermeable membrane to the other. Created by Rishi Desai.

This chemistry video tutorial explains how to calculate the molar mass from osmotic pressure. Given the osmotic pressure and the van't hoff factor, you need to calculate the molarity of the solution which can help you to determine the number of moles of solute in the solution if you know the volume of the solution.

What Is Avogadro's Number - The Mole | Chemistry for All | FuseSchool
 
04:02
Learn the basics about Avogadro's Number, as a part of chemical calculations. Avogadro’s Number or the Avogadro Constant is 6.02 X 1023 Mol-1. It is the number of atoms per mole of the carbon-12 isotope. For atoms, the mass of Avogadro’s number of particles is equal to their relative atomic mass in grams. For molecules, the mass of Avogadro’s number of particles is equal to their relative molecular mass in grams. What is Molar Volume? In 1811, Avogadro proposed his hypothesis which stated ‘Equal volumes of gases at the same temperature and pressure contain the same number of molecules’. This hypothesis made it much easier to perform calculations involving gases. So one mole (Avogadro’s number of molecules) of any gas will occupy the same volume, at the same temperature and pressure, as one mole of any other gas. The volume occupied by one mole of a gas is called the Molar Volume. Molar volume is measured in dm3mol-1. SUBSCRIBE to the Fuse School YouTube channel for many more educational videos.

It is defined as the amount of a chemical substance that contains as many elementary entities, e.g., atoms, molecules, ions, electrons, or photons, as there are atoms in 12 grams of carbon-12 (12C), the isotope of carbon with relative atomic mass 12 by definition. This number is expressed by the Avogadro constant, which has a value of 6.022140857(74)×1023 mol-1. The mole is one of the base units of the SI, and has the unit symbol mol. The mole is widely used in chemistry as a convenient way to express amounts of reactants and products of chemical reactions. For example, the chemical equation 2 H2 + O2 → 2 H2O implies that 2 mol of dihydrogen (H2) and 1 mol of dioxygen (O2) react to form 2 mol of water (H2O). The mole may also be used to express the number of atoms, ions, or other elementary entities in a given sample of any substance. The concentration of a solution is commonly expressed by its molarity, defined as the number of moles of the dissolved substance per litre of solution. While according to the official SI definition, the words "mol(es) of" should be followed by a singular word denoting a substance ("water", "oxygen"), they are commonly used by chemists with a plural word referring to elementary entities, such as atoms or electrons. In this usage,[1] mole is a number equal to 0.6022 trillion trillions, i.e. Avogadro's number. The expression "mol(es) of electrons", widely used in electrochemistry, is particularly incompatible with the SI definition since there is no 'electron substance' whose amount could be quantified. The number of molecules per mole is known as Avogadro's constant, and is defined such that the mass of one mole of a substance, expressed in grams, is equal to the mean relative molecular mass of the substance. For example, the mean relative molecular mass of natural water is about 18.015, therefore, one mole of water has a mass of about 18.015 grams. The term gram-molecule was formerly used for essentially the same concept.[2] The term gram-atom has been used for a related but distinct concept, namely a quantity of a substance that contains Avogadro's number of atoms, whether isolated or combined in molecules. Thus, for example, 1 mole of MgB2 is 1 gram-molecule of MgB2 but 3 gram-atoms of MgB2.[3][4] In honor of the unit, some chemists celebrate October 23, which is a reference to the 1023 scale of the Avogadro constant, as "Mole Day". Some also do the same for February 6 and June 2." Wikipedia contributors. "Mole (unit)." Wikipedia, The Free Encyclopedia. Wikipedia, The Free Encyclopedia, 27 Jun. 2016. Web. 2 Jul. 2016.

Polar & Non-Polar Molecules: Crash Course Chemistry #23
 
10:46
*** PLEASE WATCH WITH ANNOTATIONS ON! SOME INACCURACIES IN GRAPHICS ARE NOTED AND CORRECTED IN ANNOTATIONS. THANKS! *** Molecules come in infinite varieties, so in order to help the complicated chemical world make a little more sense, we classify and categorize them. One of the most important of those classifications is whether a molecule is polar or non-polar, which describes a kind of symmetry - not just of the molecule, but of the charge. In this edition of Crash Course Chemistry, Hank comes out for Team Polar, and describes why these molecules are so interesting to him. You'll learn that molecules need to have both charge asymmetry and geometric asymmetry to be polar, and that charge asymmetry is caused by a difference in electronegativities. You'll also learn how to notate a dipole moment (or charge separation) of a molecule, the physical mechanism behind like dissolves like, and why water is so dang good at fostering life on Earth. -- Table of Contents Charge Assymetry & Geometric Asymmetry 01:33 Difference in Electronegatives 01:49 Hank is Team Polar 00:33 Dipole Moment 03:49 Charge Separation of a Molecule 04:12 Like Dissolves Like 04:41 Water is Awesome 05:10 -- Want to find Crash Course elsewhere on the internet?

When Chemicals Meet Water: The Properties of Solutions (Accessible Preview)
 
03:52
Solutions are uniform mixtures of molecules in which any of the phases of matter can be dissolved in another phase. Whether solids, liquids, or gases, solution chemistry is important because most chemical reactions, whether in the laboratory or in nature, take place in solutions. In particular, solutions with water as the solvent are the core of all biology. Extending the particle model of matter to solutions enables chemists to predict what will happen to a deep-sea diver who breathes different mixtures of gases or to the life forms in the ocean as carbon dioxide levels rise in the atmosphere.

Jinling Sui (Flately Discovery): Building the Bioinformatic Platform for Drug Discovery
 
25:52
Building a suitable bioinformatic platform for small molecule R&D with high throughput screening (HTS) is challenging for a small biotech startup with limited experiences and resource. At Flatley Discovery Lab, we started with desktop-based data process and library management applications in our initial chemical library build-up and HTS data processing. We have grown into an Oracle-based system, and implemented additional commercial packages on the platform. The system is designed and tailored to meet exactly the need of our biologists and chemists. With desktop-based component remains to be the front end for HTS raw data processing and data QC, advanced data analysis and visualization tools are introduced to support our SAR and lead development efforts. In only a few years since its inception, Flatley Discovery Lab has discovered several exciting CFTR modulators in the development pipeline toward a new and efficacious treatment for Cystic Fibrosis.
