먼저 HOFeCrLiBeKCaScTiCPSeICoNiCuBrGaLaCePrNdPmSmHfTaW에 있는 각 원자의 수를 계산합니다.
H: 1, O: 1, Fe: 1, Cr: 1, Li: 1, Be: 1, K: 1, Ca: 1, Sc: 1, Ti: 1, C: 1, P: 1, Se: 1, I: 1, Co: 1, Ni: 1, Cu: 1, Br: 1, Ga: 1, La: 1, Ce: 1, Pr: 1, Nd: 1, Pm: 1, Sm: 1, Hf: 1, Ta: 1, W: 1
그런 다음 주기율표 의 각 원소에 대한 원자량을 검색합니다.
H: 1.00794, O: 15.9994, Fe: 55.845, Cr: 51.9961, Li: 6.941, Be: 9.012182, K: 39.0983, Ca: 40.078, Sc: 44.955912, Ti: 47.867, C: 12.0107, P: 30.973762, Se: 78.96, I: 126.90447, Co: 58.933195, Ni: 58.6934, Cu: 63.546, Br: 79.904, Ga: 69.723, La: 138.90547, Ce: 140.116, Pr: 140.90765, Nd: 144.242, Pm: 144.912749, Sm: 150.36, Hf: 178.49, Ta: 180.94788, W: 183.84
이제 원자 수와 원자량의 곱의 합을 계산합니다.
몰 질량 (HOFeCrLiBeKCaScTiCPSeICoNiCuBrGaLaCePrNdPmSmHfTaW) = ∑ Counti * Weighti =
Count(H) * Weight(H) + Count(O) * Weight(O) + Count(Fe) * Weight(Fe) + Count(Cr) * Weight(Cr) + Count(Li) * Weight(Li) + Count(Be) * Weight(Be) + Count(K) * Weight(K) + Count(Ca) * Weight(Ca) + Count(Sc) * Weight(Sc) + Count(Ti) * Weight(Ti) + Count(C) * Weight(C) + Count(P) * Weight(P) + Count(Se) * Weight(Se) + Count(I) * Weight(I) + Count(Co) * Weight(Co) + Count(Ni) * Weight(Ni) + Count(Cu) * Weight(Cu) + Count(Br) * Weight(Br) + Count(Ga) * Weight(Ga) + Count(La) * Weight(La) + Count(Ce) * Weight(Ce) + Count(Pr) * Weight(Pr) + Count(Nd) * Weight(Nd) + Count(Pm) * Weight(Pm) + Count(Sm) * Weight(Sm) + Count(Hf) * Weight(Hf) + Count(Ta) * Weight(Ta) + Count(W) * Weight(W) =
1 * 1.00794 + 1 * 15.9994 + 1 * 55.845 + 1 * 51.9961 + 1 * 6.941 + 1 * 9.012182 + 1 * 39.0983 + 1 * 40.078 + 1 * 44.955912 + 1 * 47.867 + 1 * 12.0107 + 1 * 30.973762 + 1 * 78.96 + 1 * 126.90447 + 1 * 58.933195 + 1 * 58.6934 + 1 * 63.546 + 1 * 79.904 + 1 * 69.723 + 1 * 138.90547 + 1 * 140.116 + 1 * 140.90765 + 1 * 144.242 + 1 * 144.912749 + 1 * 150.36 + 1 * 178.49 + 1 * 180.94788 + 1 * 183.84 =
2295.1711 g/mol
