We'll learn how to calculate molecular formula for a compound when you are given its empirical formula and its molar mass. In order to do this, you need to figure out what to multiply the empirical formula by to get the molecular formula and the correct molar mass. The multiple can be determined by dividing the molar mass of the compound by the molar mass of the empirical formula.
