次に、原子数と原子量の積の合計を計算します。
モル質量 (AlBCDyEuFGaHIKLaMgNOPRuSTiUVWXeYZn) = ∑ Counti * Weighti =
Count(Al) * Weight(Al) + Count(B) * Weight(B) + Count(C) * Weight(C) + Count(Dy) * Weight(Dy) + Count(Eu) * Weight(Eu) + Count(F) * Weight(F) + Count(Ga) * Weight(Ga) + Count(H) * Weight(H) + Count(I) * Weight(I) + Count(K) * Weight(K) + Count(La) * Weight(La) + Count(Mg) * Weight(Mg) + Count(N) * Weight(N) + Count(O) * Weight(O) + Count(P) * Weight(P) + Count(Ru) * Weight(Ru) + Count(S) * Weight(S) + Count(Ti) * Weight(Ti) + Count(U) * Weight(U) + Count(V) * Weight(V) + Count(W) * Weight(W) + Count(Xe) * Weight(Xe) + Count(Y) * Weight(Y) + Count(Zn) * Weight(Zn) =
