Web3 okt. 2024 · One mole of H 2 O is 6.022 x 10 23 molecules of H 2 O ( Avogadro's number). This relation is then used to 'convert' a number of H 2 O molecules to grams by the ratio: mass of X molecules of H 2 O / X molecules = mass of a mole of H 2 O molecules / 6.022 x 10 23 molecules. Solve for the mass of X molecules of H 2 O.
