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


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.
