WebOct 3, 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. WebSep 7, 2024 · One mole of water is about 18 milliliters. This is the volume of a few drops of water, 3.65 teaspoons, 1.2 tablespoons, or 0.018 liters. It’s not a large volume, yet it contains 6.022 x 1023 water molecules! You can use the same steps to find the mass and volume of any other substance.
