Empirical Formulas - Heroku
The empirical formula of an unknown compound can be derived from percent composition data, but you still will not know which compound you have. You will, however, have narrowed down the possibilities. For example, if you know the empirical formula of a compound is C 2 H 3, the molecular formula might be C 2 H 3, C 4 H 6, C 6 H 9, C 8 H 12, etc.
