WebThe empirical formula, in most cases, is not unique and is not associated with only one particular substance. For example, two substances – acetylene (C 2 H 2) and benzene (C 6 H 6) have the same empirical formula CH. This is a consequence of the fact that the ratio of carbon and hydrogen atoms in these substances is the same and equals 1:1. WebThe empirical formula of a molecule doesn’t have many uses (that I’m aware of) outside of identifying the compounds in a molecule or determining what a molecule may be if given other information. Some empirical formulas can apply to multiple molecules so there would be no way to tell what molecule is what. In order to fully identify a ...
