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.

6.89 * 10^25 molecules CO2 (1 mole / 6.022 x 10^23 molecules) (44.01 g / mole) = 5035.35 g CO2 = 5.035 kg CO2
