まず、Hg2K5NaCuSnInCoCrMoNiCNWBPSMnSi 内の各原子の数を計算します。
Hg: 2, K: 5, Na: 1, Cu: 1, Sn: 1, In: 1, Co: 1, Cr: 1, Mo: 1, Ni: 1, C: 1, N: 1, W: 1, B: 1, P: 1, S: 1, Mn: 1, Si: 1
次に、周期表の各元素の原子量を調べます。
Hg: 200.59, K: 39.0983, Na: 22.98976928, Cu: 63.546, Sn: 118.71, In: 114.818, Co: 58.933195, Cr: 51.9961, Mo: 95.96, Ni: 58.6934, C: 12.0107, N: 14.0067, W: 183.84, B: 10.811, P: 30.973762, S: 32.065, Mn: 54.938045, Si: 28.0855
次に、原子数と原子量の積の合計を計算します。
モル質量 (Hg2K5NaCuSnInCoCrMoNiCNWBPSMnSi) = ∑ Counti * Weighti =
Count(Hg) * Weight(Hg) + Count(K) * Weight(K) + Count(Na) * Weight(Na) + Count(Cu) * Weight(Cu) + Count(Sn) * Weight(Sn) + Count(In) * Weight(In) + Count(Co) * Weight(Co) + Count(Cr) * Weight(Cr) + Count(Mo) * Weight(Mo) + Count(Ni) * Weight(Ni) + Count(C) * Weight(C) + Count(N) * Weight(N) + Count(W) * Weight(W) + Count(B) * Weight(B) + Count(P) * Weight(P) + Count(S) * Weight(S) + Count(Mn) * Weight(Mn) + Count(Si) * Weight(Si) =
2 * 200.59 + 5 * 39.0983 + 1 * 22.98976928 + 1 * 63.546 + 1 * 118.71 + 1 * 114.818 + 1 * 58.933195 + 1 * 51.9961 + 1 * 95.96 + 1 * 58.6934 + 1 * 12.0107 + 1 * 14.0067 + 1 * 183.84 + 1 * 10.811 + 1 * 30.973762 + 1 * 32.065 + 1 * 54.938045 + 1 * 28.0855 =
1549.0487 g/mol
