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 or vice versa.

9.20 mol Cu3 (PO4) 2 (2 mol P / 1 mol Cu3 (PO4) 2) (6.022 x 10^23 atoms / mole P) = 1.11 x 10^25 atoms
