Empirical formulas represent the lowest whole number ratio of atoms in a compound. These calculations involve mole conversions and then using the ratio of moles as the subscripts in a chemical formula. Molecular formulas tell you the exact number of atoms in a compound and are always some whole number multiple of the empirical formula. 1. The molecular formula and empirical formula are right. As we known, empirical formula of a chemical compound is the simplest positive integer ratio of atoms present in a compound. If the compound molecular formula is C2H4Cl2, so we divide it with 2, 4, and 2 GCD / greatest common divisor. The GCD is 2, so the empirical formula is CH2Cl.
