まず、OCoFeSrMnTiNiCuLaCeSnNbAlBaGaCrCa 内の各原子の数を計算します。
O: 1, Co: 1, Fe: 1, Sr: 1, Mn: 1, Ti: 1, Ni: 1, Cu: 1, La: 1, Ce: 1, Sn: 1, Nb: 1, Al: 1, Ba: 1, Ga: 1, Cr: 1, Ca: 1
次に、周期表の各元素の原子量を調べます。
O: 15.9994, Co: 58.933195, Fe: 55.845, Sr: 87.62, Mn: 54.938045, Ti: 47.867, Ni: 58.6934, Cu: 63.546, La: 138.90547, Ce: 140.116, Sn: 118.71, Nb: 92.90638, Al: 26.9815386, Ba: 137.327, Ga: 69.723, Cr: 51.9961, Ca: 40.078
次に、原子数と原子量の積の合計を計算します。
モル質量 (OCoFeSrMnTiNiCuLaCeSnNbAlBaGaCrCa) = ∑ Counti * Weighti =
Count(O) * Weight(O) + Count(Co) * Weight(Co) + Count(Fe) * Weight(Fe) + Count(Sr) * Weight(Sr) + Count(Mn) * Weight(Mn) + Count(Ti) * Weight(Ti) + Count(Ni) * Weight(Ni) + Count(Cu) * Weight(Cu) + Count(La) * Weight(La) + Count(Ce) * Weight(Ce) + Count(Sn) * Weight(Sn) + Count(Nb) * Weight(Nb) + Count(Al) * Weight(Al) + Count(Ba) * Weight(Ba) + Count(Ga) * Weight(Ga) + Count(Cr) * Weight(Cr) + Count(Ca) * Weight(Ca) =
1 * 15.9994 + 1 * 58.933195 + 1 * 55.845 + 1 * 87.62 + 1 * 54.938045 + 1 * 47.867 + 1 * 58.6934 + 1 * 63.546 + 1 * 138.90547 + 1 * 140.116 + 1 * 118.71 + 1 * 92.90638 + 1 * 26.9815386 + 1 * 137.327 + 1 * 69.723 + 1 * 51.9961 + 1 * 40.078 =
1260.1855 g/mol
