They can be atoms, formula units (of ionic compounds), or molecules. Then—and only then—we use the balanced chemical equation to construct a conversion factor to convert that quantity to moles of another substance, which in turn can be converted to a corresponding mass. We do it by using mass rather than by counting individual atoms. To calculate formula or molecular masses, it is important that you keep track of the number of atoms of each element in the molecular formula to obtain the correct molecular mass. 00174% iron, how many moles of iron are in an average female? 22H2 + 11O2 → 22H2O.
