まず、SO3Cl4BrAgAuAtThRhUMoLiNaKAlGe 内の各原子の数を計算します。
S: 1, O: 3, Cl: 4, Br: 1, Ag: 1, Au: 1, At: 1, Th: 1, Rh: 1, U: 1, Mo: 1, Li: 1, Na: 1, K: 1, Al: 1, Ge: 1
次に、周期表の各元素の原子量を調べます。
S: 32.065, O: 15.9994, Cl: 35.453, Br: 79.904, Ag: 107.8682, Au: 196.966569, At: 209.987148, Th: 232.03806, Rh: 102.9055, U: 238.02891, Mo: 95.96, Li: 6.941, Na: 22.98976928, K: 39.0983, Al: 26.9815386, Ge: 72.64
次に、原子数と原子量の積の合計を計算します。
モル質量 (SO3Cl4BrAgAuAtThRhUMoLiNaKAlGe) = ∑ Counti * Weighti =
Count(S) * Weight(S) + Count(O) * Weight(O) + Count(Cl) * Weight(Cl) + Count(Br) * Weight(Br) + Count(Ag) * Weight(Ag) + Count(Au) * Weight(Au) + Count(At) * Weight(At) + Count(Th) * Weight(Th) + Count(Rh) * Weight(Rh) + Count(U) * Weight(U) + Count(Mo) * Weight(Mo) + Count(Li) * Weight(Li) + Count(Na) * Weight(Na) + Count(K) * Weight(K) + Count(Al) * Weight(Al) + Count(Ge) * Weight(Ge) =
1 * 32.065 + 3 * 15.9994 + 4 * 35.453 + 1 * 79.904 + 1 * 107.8682 + 1 * 196.966569 + 1 * 209.987148 + 1 * 232.03806 + 1 * 102.9055 + 1 * 238.02891 + 1 * 95.96 + 1 * 6.941 + 1 * 22.98976928 + 1 * 39.0983 + 1 * 26.9815386 + 1 * 72.64 =
1654.1842 g/mol
