次に、原子数と原子量の積の合計を計算します。
モル質量 (MnNaNO3ClIBrSTcNoCuCoUPu12SnNiBiBPKHErC) = ∑ Counti * Weighti =
Count(Mn) * Weight(Mn) + Count(Na) * Weight(Na) + Count(N) * Weight(N) + Count(O) * Weight(O) + Count(Cl) * Weight(Cl) + Count(I) * Weight(I) + Count(Br) * Weight(Br) + Count(S) * Weight(S) + Count(Tc) * Weight(Tc) + Count(No) * Weight(No) + Count(Cu) * Weight(Cu) + Count(Co) * Weight(Co) + Count(U) * Weight(U) + Count(Pu) * Weight(Pu) + Count(Sn) * Weight(Sn) + Count(Ni) * Weight(Ni) + Count(Bi) * Weight(Bi) + Count(B) * Weight(B) + Count(P) * Weight(P) + Count(K) * Weight(K) + Count(H) * Weight(H) + Count(Er) * Weight(Er) + Count(C) * Weight(C) =
1 * 54.938045 + 1 * 22.98976928 + 1 * 14.0067 + 3 * 15.9994 + 1 * 35.453 + 1 * 126.90447 + 1 * 79.904 + 1 * 32.065 + 1 * 96.906365 + 1 * 259.10103 + 1 * 63.546 + 1 * 58.933195 + 1 * 238.02891 + 12 * 238.0495599 + 1 * 118.71 + 1 * 58.6934 + 1 * 208.9804 + 1 * 10.811 + 1 * 30.973762 + 1 * 39.0983 + 1 * 1.00794 + 1 * 167.259 + 1 * 12.0107 =
