Lucas Kinsey Chemistry 211 Week 3 Notes Chapter 3 Stoichiometry of Formulas and Equations Stoichiometry: the study of the quantitative aspects of formulas and reactions Mole (mol): the amount of a substance that contains the same number of entities as the number of atoms in 12 g of Carbon-12 # of atoms in 12g of Carbon 12 = Avogadro’s Number Avogadro’s Number: 1 mol = 6.022x 10 23 - Moles relate the number of entities to the mass of the sample of entities - Moles maintain the same numerical relationship between amu and mass in grams on the macroscopic scale Molar Mass ( μ ): mass per mole (g/mol) Ways to find molar mass: 1. With Elements: find atomic mass on periodic ta
