Avogadro's number represents the number of units in one mole of any substance. This has the value of 6.022 x 10^23 units / mole. This number can be used to convert the number of atoms or molecules into number of moles. Calculations are as follows:

2.50 mol FeWO4 (1 mol Fe / 1 mol FeWO4) (6.022 x 10^23 atoms Fe / 1 mol Fe) = 1.51 x 10^24 atoms Fe
