WebEmpirical Formulas. An empirical formula tells us the relative ratios of different atoms in a compound. The ratios hold true on the molar level as well. Thus, H 2 O is composed of two atoms of hydrogen and 1 atom of oxygen. Likewise, 1.0 mole of H 2 O is composed of … Therefore, for ionic compounds, the formula mass (also called the empirical formula … WebMolecular or molar mass (amu or g/mol) / empirical formula mass (amu or g/mol) = n formula units/molecules. The molecular formula is then obtained by multiplying each subscript in the empirical formula by n, as shown by the generic empirical formula AxBy. (A x B y) n = A nx B ny. N, x, and y are subscripts.
