A formula unit is the chemical formula representing an ionic compound in its simplest and most reduced terms. It is related to the concept of an empirical formula, which is the simplest chemical formula expression for a non-ionic chemical compound. Empirical formulas reduce molecules to their simplest ratio of atoms.

To convert moles of a chemical substance to formula units, first convert moles into grams by using the molar masses of the elements that form the chemical compound. Every element in a chemical substance has its own molar mass, which is measured in grams. Many chemical substances are compounds formed from combinations of moles of various elements.
The molecular mass, or molecular weight of a compound (measured in atomic mass units, amu) is obtained by adding up the atomic masses of all of the atoms present within a unit of the substance. For ionic compounds, the term formula mass or formula weight is used instead, since there aren't really any molecules present.
