What is Empirical formula mass?
The empirical formula mass is the sum of the relative atomic masses of the atoms shown in a compound's empirical formula; dividing the compound's relative molecular mass by it gives the whole-number multiplier that converts the empirical formula into the molecular formula.
This definition is part of the Stoichiometry chapter in Cambridge O Level Chemistry.
