Stoichiometry 1 amu = 1.6606 x 10-24 g The amu mass of an atom of carbon-12 is 12 amu 1 mole = count multiplier = 6.022 x 1023 items subscript to the right of an element symbol = atom count multiplier = the number of atoms of the element in a chemical formula number before chemical formula in a chemical reaction = formula count multiplier = the number of formula units required for the balanced chemical reaction Recall for compound MaAb: measured mass of atom M/ measured mass of atom A = a x atomic weight of M/ b x atomic weight of A and can be rearranged to measured mass of atom M/ a x atomic weight of M = measured mass of atom A/ b x atomic weight of A = moles M/a = moles A/b
