• empirical and molecular formulas can be determined from mass percent composition data and combustion analysis data to determine an empirical formula : 1. determine the quantity (in moles) of each element present 2. determine the mole ratio of the elements present in the smallest possible whole numbers to determine the molecular formula : 3. divide.

The percent composition is a ratio between the mass contributions from each the elements in a compound and the mass of the entire compound. If the ratios between the elements are the same for the empirical and molecular formulas, then the percent compositions would be the same.

Besides, any two compounds can have the same empirical formula. This is one more reason for not considering empirical formula as the molecular formula.
