Web30 nov. 2024 · For sodium chloride, it's equal to 58.44 g/mol (as Na = 22.99 g/mol and Cl = 35.45 g/mol). Convert grams to moles. Use the formula moles = mass of solute / molar mass. Assume we want to dissolve 70.128 grams of salt in 1.5 kg of water. So: moles of NaCl = 70.128 g / (58.44 g/mol) = 1.2 mol. 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
