By using molar masses, the information in a chemical formula can be used to determine the relative masses of each kind of element in a compound.

The total mass of a sample of a compound can be related to the masses of the constituent elements contained in the compound. We can refer to the relative masses of each kind of element within a compound to determine the empirical formula of the compound.

If the chemist also knows the molar mass of the compound, he or she can also determine its molecular formula. In order to relate the mass and number of. Mass and Moles of Substance A. Molecular Mass and Formula Mass. Section 3. Just as we can talk about mass of one atom of.
