Well, it's used to define elemental composition and percentage.

Explanation:

Whether you learn how to do it is of course your choice. Empirical formulae provide the simplest whole number ratio that defines constituent atoms in a species. Given an empirical formula, and a molecular mass estimate, an analyst can calculate a molecular formula. Thus combustion analysis, a fairly simple and accessible experiment, can give a chemical formula directly.
