WebSo for example he fist multiples the mass of potassium in grams (0.099g of K) by the molar mass of potassium. But he doesn't multiply simply by 39.10 g/mol as the periodic table gave him, he takes the reciprocal of the molar mass so that the unit grams of K cross cancel and his answer will have units of moles of K. WebTo calculate the molar mass of a molecule, we add the molar mass of each constituent atom by the corresponding subscript. For example, the molar mass of water would be: M (H 2 O) = 2 x 1.0 + 16.0 = 18.0 g/mol If the formula of the molecule is not given, you will need to first determine it. diaper changing table toolbox
