まず、AuAgFeKNOCLiSHeHBrCrCoYbCeCaNbRb 内の各原子の数を計算します。
Au: 1, Ag: 1, Fe: 1, K: 1, N: 1, O: 1, C: 1, Li: 1, S: 1, He: 1, H: 1, Br: 1, Cr: 1, Co: 1, Yb: 1, Ce: 1, Ca: 1, Nb: 1, Rb: 1
次に、周期表の各元素の原子量を調べます。
Au: 196.966569, Ag: 107.8682, Fe: 55.845, K: 39.0983, N: 14.0067, O: 15.9994, C: 12.0107, Li: 6.941, S: 32.065, He: 4.002602, H: 1.00794, Br: 79.904, Cr: 51.9961, Co: 58.933195, Yb: 173.054, Ce: 140.116, Ca: 40.078, Nb: 92.90638, Rb: 85.4678
次に、原子数と原子量の積の合計を計算します。
モル質量 (AuAgFeKNOCLiSHeHBrCrCoYbCeCaNbRb) = ∑ Counti * Weighti =
Count(Au) * Weight(Au) + Count(Ag) * Weight(Ag) + Count(Fe) * Weight(Fe) + Count(K) * Weight(K) + Count(N) * Weight(N) + Count(O) * Weight(O) + Count(C) * Weight(C) + Count(Li) * Weight(Li) + Count(S) * Weight(S) + Count(He) * Weight(He) + Count(H) * Weight(H) + Count(Br) * Weight(Br) + Count(Cr) * Weight(Cr) + Count(Co) * Weight(Co) + Count(Yb) * Weight(Yb) + Count(Ce) * Weight(Ce) + Count(Ca) * Weight(Ca) + Count(Nb) * Weight(Nb) + Count(Rb) * Weight(Rb) =
1 * 196.966569 + 1 * 107.8682 + 1 * 55.845 + 1 * 39.0983 + 1 * 14.0067 + 1 * 15.9994 + 1 * 12.0107 + 1 * 6.941 + 1 * 32.065 + 1 * 4.002602 + 1 * 1.00794 + 1 * 79.904 + 1 * 51.9961 + 1 * 58.933195 + 1 * 173.054 + 1 * 140.116 + 1 * 40.078 + 1 * 92.90638 + 1 * 85.4678 =
1208.2669 g/mol
