Converting Between Moles, Mass, & Particles (van Geel, 12:16)
-Several examples of these types of problems, which form the basis for most chemistry calculations. EXTREMELY IMPORTANT to understand.
Percent Composition (van Geel, 5:29)
-How to determine the % makeup of each atom from a chemical formula
Empirical Formulas (van Geel, 8:40)
-Given the percent composition, how to find a substance's empirical formula (the most "reduced" formula)
Molecular Formulas (van Geel, 4:57)
-How to find a substance's molecular formula, knowing its empirical formula and its approximate molar mass.
