Khan Academy: The Mole and Avogadro's Number
An explanation the mole (named for molecule) and Avogadro's Number. One mole of a substance is equal to 6.022 times 10 to 23rd power units of that substance (such as atoms, molecules, or ions). The number 6.022 time 10 to 23rd power is...

Serc: Mn Step: Stoichiometry: Introduction to Stoichiometry
Using the example of a cake recipe, young scholars find the ratios between different ingredients, which introduces the concept of mole ratios. They then calculate the mole ratios in a chemical equation, and learn how this applies to...
Khan Academy
Khan Academy: Molarity vs.osmolarity
Molarity and osmolarity 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....
