<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 calculate as follows:
</span>2.0x10^22 molecules H2O ( 1 mol / 6.022 x 10^23 molecules ) = 0.0332 moles H2O
