まず、HHeBeLiBCNOFNeNaAlArAuAgU208 内の各原子の数を計算します。
H: 1, He: 1, Be: 1, Li: 1, B: 1, C: 1, N: 1, O: 1, F: 1, Ne: 1, Na: 1, Al: 1, Ar: 1, Au: 1, Ag: 1, U: 208
次に、周期表の各元素の原子量を調べます。
H: 1.00794, He: 4.002602, Be: 9.012182, Li: 6.941, B: 10.811, C: 12.0107, N: 14.0067, O: 15.9994, F: 18.9984032, Ne: 20.1797, Na: 22.98976928, Al: 26.9815386, Ar: 39.948, Au: 196.966569, Ag: 107.8682, U: 238.02891
次に、原子数と原子量の積の合計を計算します。
モル質量 (HHeBeLiBCNOFNeNaAlArAuAgU208) = ∑ Counti * Weighti =
Count(H) * Weight(H) + Count(He) * Weight(He) + Count(Be) * Weight(Be) + Count(Li) * Weight(Li) + Count(B) * Weight(B) + Count(C) * Weight(C) + Count(N) * Weight(N) + Count(O) * Weight(O) + Count(F) * Weight(F) + Count(Ne) * Weight(Ne) + Count(Na) * Weight(Na) + Count(Al) * Weight(Al) + Count(Ar) * Weight(Ar) + Count(Au) * Weight(Au) + Count(Ag) * Weight(Ag) + Count(U) * Weight(U) =
1 * 1.00794 + 1 * 4.002602 + 1 * 9.012182 + 1 * 6.941 + 1 * 10.811 + 1 * 12.0107 + 1 * 14.0067 + 1 * 15.9994 + 1 * 18.9984032 + 1 * 20.1797 + 1 * 22.98976928 + 1 * 26.9815386 + 1 * 39.948 + 1 * 196.966569 + 1 * 107.8682 + 208 * 238.02891 =
