まず、AuOSUCaEuTaWHgHHeKrCeRaCuNeGaPoMo 内の各原子の数を計算します。
Au: 1, O: 1, S: 1, U: 1, Ca: 1, Eu: 1, Ta: 1, W: 1, Hg: 1, H: 1, He: 1, Kr: 1, Ce: 1, Ra: 1, Cu: 1, Ne: 1, Ga: 1, Po: 1, Mo: 1
次に、周期表の各元素の原子量を調べます。
Au: 196.966569, O: 15.9994, S: 32.065, U: 238.02891, Ca: 40.078, Eu: 151.964, Ta: 180.94788, W: 183.84, Hg: 200.59, H: 1.00794, He: 4.002602, Kr: 83.798, Ce: 140.116, Ra: 226.0254098, Cu: 63.546, Ne: 20.1797, Ga: 69.723, Po: 208.9824304, Mo: 95.96
次に、原子数と原子量の積の合計を計算します。
モル質量 (AuOSUCaEuTaWHgHHeKrCeRaCuNeGaPoMo) = ∑ Counti * Weighti =
Count(Au) * Weight(Au) + Count(O) * Weight(O) + Count(S) * Weight(S) + Count(U) * Weight(U) + Count(Ca) * Weight(Ca) + Count(Eu) * Weight(Eu) + Count(Ta) * Weight(Ta) + Count(W) * Weight(W) + Count(Hg) * Weight(Hg) + Count(H) * Weight(H) + Count(He) * Weight(He) + Count(Kr) * Weight(Kr) + Count(Ce) * Weight(Ce) + Count(Ra) * Weight(Ra) + Count(Cu) * Weight(Cu) + Count(Ne) * Weight(Ne) + Count(Ga) * Weight(Ga) + Count(Po) * Weight(Po) + Count(Mo) * Weight(Mo) =
1 * 196.966569 + 1 * 15.9994 + 1 * 32.065 + 1 * 238.02891 + 1 * 40.078 + 1 * 151.964 + 1 * 180.94788 + 1 * 183.84 + 1 * 200.59 + 1 * 1.00794 + 1 * 4.002602 + 1 * 83.798 + 1 * 140.116 + 1 * 226.0254098 + 1 * 63.546 + 1 * 20.1797 + 1 * 69.723 + 1 * 208.9824304 + 1 * 95.96 =
2153.8208 g/mol
