먼저 NaOCrSH2FeClCaCdPAlCe6Nb2WF86NdAg102Au2VCoC에 있는 각 원자의 수를 계산합니다.
Na: 1, O: 1, Cr: 1, S: 1, H: 2, Fe: 1, Cl: 1, Ca: 1, Cd: 1, P: 1, Al: 1, Ce: 6, Nb: 2, W: 1, F: 86, Nd: 1, Ag: 102, Au: 2, V: 1, Co: 1, C: 1
그런 다음 주기율표 의 각 원소에 대한 원자량을 검색합니다.
Na: 22.98976928, O: 15.9994, Cr: 51.9961, S: 32.065, H: 1.00794, Fe: 55.845, Cl: 35.453, Ca: 40.078, Cd: 112.411, P: 30.973762, Al: 26.9815386, Ce: 140.116, Nb: 92.90638, W: 183.84, F: 18.9984032, Nd: 144.242, Ag: 107.8682, Au: 196.966569, V: 50.9415, Co: 58.933195, C: 12.0107
이제 원자 수와 원자량의 곱의 합을 계산합니다.
몰 질량 (NaOCrSH2FeClCaCdPAlCe6Nb2WF86NdAg102Au2VCoC) = ∑ Counti * Weighti =
Count(Na) * Weight(Na) + Count(O) * Weight(O) + Count(Cr) * Weight(Cr) + Count(S) * Weight(S) + Count(H) * Weight(H) + Count(Fe) * Weight(Fe) + Count(Cl) * Weight(Cl) + Count(Ca) * Weight(Ca) + Count(Cd) * Weight(Cd) + Count(P) * Weight(P) + Count(Al) * Weight(Al) + Count(Ce) * Weight(Ce) + Count(Nb) * Weight(Nb) + Count(W) * Weight(W) + Count(F) * Weight(F) + Count(Nd) * Weight(Nd) + Count(Ag) * Weight(Ag) + Count(Au) * Weight(Au) + Count(V) * Weight(V) + Count(Co) * Weight(Co) + Count(C) * Weight(C) =
1 * 22.98976928 + 1 * 15.9994 + 1 * 51.9961 + 1 * 32.065 + 2 * 1.00794 + 1 * 55.845 + 1 * 35.453 + 1 * 40.078 + 1 * 112.411 + 1 * 30.973762 + 1 * 26.9815386 + 6 * 140.116 + 2 * 92.90638 + 1 * 183.84 + 86 * 18.9984032 + 1 * 144.242 + 102 * 107.8682 + 2 * 196.966569 + 1 * 50.9415 + 1 * 58.933195 + 1 * 12.0107 =
