In chemistry, the empirical formula of a chemical is a simple expression of the relative number of each type of atom or ratio of the elements in the compound. Empirical formulas are the standard for ionic compounds, such as CaCl 2, and for macromolecules, such as SiO 2.An empirical formula makes no reference to isomerism, structure, or absolute number of atoms.
