まず、FeZnCuAuONeXeArCUPtPaPCaHHeEr 内の各原子の数を計算します。
Fe: 1, Zn: 1, Cu: 1, Au: 1, O: 1, Ne: 1, Xe: 1, Ar: 1, C: 1, U: 1, Pt: 1, Pa: 1, P: 1, Ca: 1, H: 1, He: 1, Er: 1
次に、周期表の各元素の原子量を調べます。
Fe: 55.845, Zn: 65.38, Cu: 63.546, Au: 196.966569, O: 15.9994, Ne: 20.1797, Xe: 131.293, Ar: 39.948, C: 12.0107, U: 238.02891, Pt: 195.084, Pa: 231.03588, P: 30.973762, Ca: 40.078, H: 1.00794, He: 4.002602, Er: 167.259
次に、原子数と原子量の積の合計を計算します。
モル質量 (FeZnCuAuONeXeArCUPtPaPCaHHeEr) = ∑ Counti * Weighti =
Count(Fe) * Weight(Fe) + Count(Zn) * Weight(Zn) + Count(Cu) * Weight(Cu) + Count(Au) * Weight(Au) + Count(O) * Weight(O) + Count(Ne) * Weight(Ne) + Count(Xe) * Weight(Xe) + Count(Ar) * Weight(Ar) + Count(C) * Weight(C) + Count(U) * Weight(U) + Count(Pt) * Weight(Pt) + Count(Pa) * Weight(Pa) + Count(P) * Weight(P) + Count(Ca) * Weight(Ca) + Count(H) * Weight(H) + Count(He) * Weight(He) + Count(Er) * Weight(Er) =
1 * 55.845 + 1 * 65.38 + 1 * 63.546 + 1 * 196.966569 + 1 * 15.9994 + 1 * 20.1797 + 1 * 131.293 + 1 * 39.948 + 1 * 12.0107 + 1 * 238.02891 + 1 * 195.084 + 1 * 231.03588 + 1 * 30.973762 + 1 * 40.078 + 1 * 1.00794 + 1 * 4.002602 + 1 * 167.259 =
1508.6385 g/mol
