General Chemistry - Stoichiometry: Calculating with Moles | 3.2 General Chemistry

Stoichiometry Basics: Calculations with Moles Chad covers calculations with moles in this lesson. The mole is first defined as Avogadro's number (6.022x10^23) and it is shown how to use Avogadro's number to calculate from moles to molecules, moles to atoms or from molecules to moles or atoms to moles. Chad then compares and contrasts four terms: atomic weight, molecular weight, formula weight, and molar mass. It is then shown how these can be calculated from the periodic table and then used to convert grams to moles or moles to grams. Finally, Chad shows how a chemical formula provides mole-to-mole ratios of the different atoms a compound is composed of and how these are used to determine the number of atoms or moles of one to the number of atoms or moles of another. Several mole-to-mole ratio practice problems have been completed. I've embedded this playlist as a course on my website with all the lessons organized by chapter in a collapsible menu and much of the content from the study guide included on the page.
