まず、LiAgNSiAuAlAgHgHCBUBeISNaMnH 内の各原子の数を計算します。
Li: 1, Ag: 2, N: 1, Si: 1, Au: 1, Al: 1, Hg: 1, H: 2, C: 1, B: 1, U: 1, Be: 1, I: 1, S: 1, Na: 1, Mn: 1
次に、周期表の各元素の原子量を調べます。
Li: 6.941, Ag: 107.8682, N: 14.0067, Si: 28.0855, Au: 196.966569, Al: 26.9815386, Hg: 200.59, H: 1.00794, C: 12.0107, B: 10.811, U: 238.02891, Be: 9.012182, I: 126.90447, S: 32.065, Na: 22.98976928, Mn: 54.938045
次に、原子数と原子量の積の合計を計算します。
モル質量 (LiAgNSiAuAlAgHgHCBUBeISNaMnH) = ∑ Counti * Weighti =
Count(Li) * Weight(Li) + Count(Ag) * Weight(Ag) + Count(N) * Weight(N) + Count(Si) * Weight(Si) + Count(Au) * Weight(Au) + Count(Al) * Weight(Al) + Count(Hg) * Weight(Hg) + Count(H) * Weight(H) + Count(C) * Weight(C) + Count(B) * Weight(B) + Count(U) * Weight(U) + Count(Be) * Weight(Be) + Count(I) * Weight(I) + Count(S) * Weight(S) + Count(Na) * Weight(Na) + Count(Mn) * Weight(Mn) =
1 * 6.941 + 2 * 107.8682 + 1 * 14.0067 + 1 * 28.0855 + 1 * 196.966569 + 1 * 26.9815386 + 1 * 200.59 + 2 * 1.00794 + 1 * 12.0107 + 1 * 10.811 + 1 * 238.02891 + 1 * 9.012182 + 1 * 126.90447 + 1 * 32.065 + 1 * 22.98976928 + 1 * 54.938045 =
1198.0837 g/mol
