2017-05-17 · Empirical Formula – This is the simplest formula that shows the simplest whole number ratio of atoms of different elements in a molecule. e.g. Benzene empirical formula is CH.This formula shows that in benzene molecule, the ratio of carbon atoms to hydrogen atoms is 1:1 , i.e the # of C-atoms = # of H-atoms. Solving Empirical Formula Problems There are two common types of empirical formula problems. Luckily, the steps to solve either are almost exactly the same. Example #1: Given mass % of elements in a compound.
