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:

 
2.0x10^22 molecules H2O ( 1 mol /  6.022 x 10^23 molecules ) = 0.0332 moles H2O

Hope this answers the question. Have a nice day.
