10. The ratio is therefore 1:2:1 so the empirical formula is CH20-simplify the molecular formula. for example take C6H1206 and divide each coefficient by the smallest number (6) → CH20-if you are given the masses of each element in the compound you divide the masses by the Ar, and convert into the simplest whole number ratio.
