まず、Zn4O2N1H42S2CuRnAtP2AgPoAuSnPbBiTlHg 内の各原子の数を計算します。
Zn: 4, O: 2, N: 1, H: 42, S: 2, Cu: 1, Rn: 1, At: 1, P: 2, Ag: 1, Po: 1, Au: 1, Sn: 1, Pb: 1, Bi: 1, Tl: 1, Hg: 1
次に、周期表の各元素の原子量を調べます。
Zn: 65.38, O: 15.9994, N: 14.0067, H: 1.00794, S: 32.065, Cu: 63.546, Rn: 210.990601, At: 209.987148, P: 30.973762, Ag: 107.8682, Po: 208.9824304, Au: 196.966569, Sn: 118.71, Pb: 207.2, Bi: 208.9804, Tl: 204.3833, Hg: 200.59
次に、原子数と原子量の積の合計を計算します。
モル質量 (Zn4O2N1H42S2CuRnAtP2AgPoAuSnPbBiTlHg) = ∑ Counti * Weighti =
Count(Zn) * Weight(Zn) + Count(O) * Weight(O) + Count(N) * Weight(N) + Count(H) * Weight(H) + Count(S) * Weight(S) + Count(Cu) * Weight(Cu) + Count(Rn) * Weight(Rn) + Count(At) * Weight(At) + Count(P) * Weight(P) + Count(Ag) * Weight(Ag) + Count(Po) * Weight(Po) + Count(Au) * Weight(Au) + Count(Sn) * Weight(Sn) + Count(Pb) * Weight(Pb) + Count(Bi) * Weight(Bi) + Count(Tl) * Weight(Tl) + Count(Hg) * Weight(Hg) =
4 * 65.38 + 2 * 15.9994 + 1 * 14.0067 + 42 * 1.00794 + 2 * 32.065 + 1 * 63.546 + 1 * 210.990601 + 1 * 209.987148 + 2 * 30.973762 + 1 * 107.8682 + 1 * 208.9824304 + 1 * 196.966569 + 1 * 118.71 + 1 * 207.2 + 1 * 208.9804 + 1 * 204.3833 + 1 * 200.59 =
2414.1412 g/mol
