次に、周期表の各元素の原子量を調べます。
Na: 22.98976928, Cl: 35.453, Pb: 207.2, K: 39.0983, F: 18.9984032, Li: 6.941, Mg: 24.305, Ga: 69.723, Hg: 200.59, I: 126.90447, La: 138.90547, Ce: 140.116, Pr: 140.90765, Ac: 227.0277521, Th: 232.03806, Pa: 231.03588, Nd: 144.242, U: 238.02891
次に、原子数と原子量の積の合計を計算します。
モル質量 (NaClPbKFLiMgGaHgILaCePrAcThPaNdU) = ∑ Counti * Weighti =
Count(Na) * Weight(Na) + Count(Cl) * Weight(Cl) + Count(Pb) * Weight(Pb) + Count(K) * Weight(K) + Count(F) * Weight(F) + Count(Li) * Weight(Li) + Count(Mg) * Weight(Mg) + Count(Ga) * Weight(Ga) + Count(Hg) * Weight(Hg) + Count(I) * Weight(I) + Count(La) * Weight(La) + Count(Ce) * Weight(Ce) + Count(Pr) * Weight(Pr) + Count(Ac) * Weight(Ac) + Count(Th) * Weight(Th) + Count(Pa) * Weight(Pa) + Count(Nd) * Weight(Nd) + Count(U) * Weight(U) =
