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.

12 g CuBr2 (1 mol / 223.37 g) (6.022 x 10^23 molecules / mole) = 3.24x10^22 molecules CuBr2
