次に、周期表の各元素の原子量を調べます。
I: 126.90447, Cl: 35.453, Na: 22.98976928, P: 30.973762, Xe: 131.293, H: 1.00794, O: 15.9994, C: 12.0107, U: 238.02891, Zn: 65.38, Cu: 63.546, Ag: 107.8682, Au: 196.966569, Ra: 226.0254098, Ga: 69.723, Hg: 200.59, S: 32.065, N: 14.0067, Kr: 83.798
次に、原子数と原子量の積の合計を計算します。
モル質量 (ICl6Na9P4XeH6O3C4UZnCuAgAuRaGa2HgSNKr2) = ∑ Counti * Weighti =
Count(I) * Weight(I) + Count(Cl) * Weight(Cl) + Count(Na) * Weight(Na) + Count(P) * Weight(P) + Count(Xe) * Weight(Xe) + Count(H) * Weight(H) + Count(O) * Weight(O) + Count(C) * Weight(C) + Count(U) * Weight(U) + Count(Zn) * Weight(Zn) + Count(Cu) * Weight(Cu) + Count(Ag) * Weight(Ag) + Count(Au) * Weight(Au) + Count(Ra) * Weight(Ra) + Count(Ga) * Weight(Ga) + Count(Hg) * Weight(Hg) + Count(S) * Weight(S) + Count(N) * Weight(N) + Count(Kr) * Weight(Kr) =
1 * 126.90447 + 6 * 35.453 + 9 * 22.98976928 + 4 * 30.973762 + 1 * 131.293 + 6 * 1.00794 + 3 * 15.9994 + 4 * 12.0107 + 1 * 238.02891 + 1 * 65.38 + 1 * 63.546 + 1 * 107.8682 + 1 * 196.966569 + 1 * 226.0254098 + 2 * 69.723 + 1 * 200.59 + 1 * 32.065 + 1 * 14.0067 + 2 * 83.798 =
2355.3259 g/mol
