Use (and memorize) this formula. n = m/M; where n = moles, m = mass, and M = molar mass. From this formula, you can also calculate mass (m = n × M) and molar mass (M = m/n) if you know the other two values. m (H₂O) = 72 g M (H₂O) = (2 × 1.008 g/mol H) + 15.999 g/mol O = 18.015 g/mol eahs form st martinWeb500 = 500. 1000 = 1000. 5000 = 5000. The gram (British spelling: gramme, abbreviation: g) is a unit of mass in the SI system (metric system).
