<span>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. We do as follows:

</span>3.0 x 10^24 atoms N2 ( 1 mol / 6.022 x 10^23 atoms ) = 4.98 moles or 5.0 moles of N2
