Molar mass • Molar mass of a substance = mass in grams of one mole of the substance. • A compound’s molar mass is NUMERICALLY equal to its formula mass. 2 mol H x 1.01 g H = 2.02 g H 1 mol H 1 mol O x 16.00 g O = 16.00 g O 1 mol O molar mass H 2 O = 18.02...
the compound and using the formula whole part mass = % for each element in the compound. The part is the mass of each individual element while the whole is the molar mass. If you know the molar mass and mass percents you can determine the empirical and molecular formula of the compounds...
