In chemistry, the empirical formula of a chemical compound is the simplest positive integer ratio of atoms present in a compound. A simple. However, their molecular formulas, which express the number of atoms in each molecule of a chemical compound, are not the same. An empirical formula. Step 1: Change each percentage to an expression of the mass of each element in grams. That is, 48.64% C.
