まず、C8Tl2OH3MnRnHeKPbLi4FAuSiXeFeHgAr 内の各原子の数を計算します。
C: 8, Tl: 2, O: 1, H: 3, Mn: 1, Rn: 1, He: 1, K: 1, Pb: 1, Li: 4, F: 1, Au: 1, Si: 1, Xe: 1, Fe: 1, Hg: 1, Ar: 1
次に、周期表の各元素の原子量を調べます。
C: 12.0107, Tl: 204.3833, O: 15.9994, H: 1.00794, Mn: 54.938045, Rn: 210.990601, He: 4.002602, K: 39.0983, Pb: 207.2, Li: 6.941, F: 18.9984032, Au: 196.966569, Si: 28.0855, Xe: 131.293, Fe: 55.845, Hg: 200.59, Ar: 39.948
次に、原子数と原子量の積の合計を計算します。
モル質量 (C8Tl2OH3MnRnHeKPbLi4FAuSiXeFeHgAr) = ∑ Counti * Weighti =
Count(C) * Weight(C) + Count(Tl) * Weight(Tl) + Count(O) * Weight(O) + Count(H) * Weight(H) + Count(Mn) * Weight(Mn) + Count(Rn) * Weight(Rn) + Count(He) * Weight(He) + Count(K) * Weight(K) + Count(Pb) * Weight(Pb) + Count(Li) * Weight(Li) + Count(F) * Weight(F) + Count(Au) * Weight(Au) + Count(Si) * Weight(Si) + Count(Xe) * Weight(Xe) + Count(Fe) * Weight(Fe) + Count(Hg) * Weight(Hg) + Count(Ar) * Weight(Ar) =
8 * 12.0107 + 2 * 204.3833 + 1 * 15.9994 + 3 * 1.00794 + 1 * 54.938045 + 1 * 210.990601 + 1 * 4.002602 + 1 * 39.0983 + 1 * 207.2 + 4 * 6.941 + 1 * 18.9984032 + 1 * 196.966569 + 1 * 28.0855 + 1 * 131.293 + 1 * 55.845 + 1 * 200.59 + 1 * 39.948 =
