Iz tega sledi, da je molska masa neona M(Ne) = 20.2 g/mol. Pri izračunu molske mase večatomnih molekul (elementov in spojin) moramo upoštevati število posameznih atomov v molekuli. Tako je relativna atomska masa vodika A<sub>r</sub>(H) = 1.0, relativna atomska masa kisika pa A<sub>r</sub>(O) = 16.0. Iz tega sledi, da je relativna molekulska masa vode M<sub>r</sub>(H<sub>2</sub>O) = 2·1.0 + 16.0 = 18.0. Molska masa vode pa je M(H<sub>2</sub>O) = 18.0 g/mol.</p>
