An empirical formula is the simplest ratio of the different types of atom in a compound.

The empirical formula of a compound may not be the same as the chemical formula:

Empirical formulae are calculated from the amount of atoms in a chemical reaction.

The number of atoms can be found if you know the mass of different elements and the relative atomic mass of the elements in the reaction.
