    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.

    0.25 mol NO2 (1 mol N / 1 NO2) (6.022 x 10^23 atoms / mol) = 1.5055x10^23 atoms
