Najpierw oblicz liczbę każdego atomu w HLiNaKRbCsBeMgCaSrBaScYLaTiZrAgAuZnCdHgBAlGaInCSiGeSnPbNPAs:
H: 1, Li: 1, Na: 1, K: 1, Rb: 1, Cs: 1, Be: 1, Mg: 1, Ca: 1, Sr: 1, Ba: 1, Sc: 1, Y: 1, La: 1, Ti: 1, Zr: 1, Ag: 1, Au: 1, Zn: 1, Cd: 1, Hg: 1, B: 1, Al: 1, Ga: 1, In: 1, C: 1, Si: 1, Ge: 1, Sn: 1, Pb: 1, N: 1, P: 1, As: 1
Następnie wyszukaj masy atomowe każdego pierwiastka w układzie okresowym :
H: 1.00794, Li: 6.941, Na: 22.98976928, K: 39.0983, Rb: 85.4678, Cs: 132.9054519, Be: 9.012182, Mg: 24.305, Ca: 40.078, Sr: 87.62, Ba: 137.327, Sc: 44.955912, Y: 88.90585, La: 138.90547, Ti: 47.867, Zr: 91.224, Ag: 107.8682, Au: 196.966569, Zn: 65.38, Cd: 112.411, Hg: 200.59, B: 10.811, Al: 26.9815386, Ga: 69.723, In: 114.818, C: 12.0107, Si: 28.0855, Ge: 72.64, Sn: 118.71, Pb: 207.2, N: 14.0067, P: 30.973762, As: 74.9216
Teraz oblicz sumę iloczynów liczby atomów do masy atomowej:
Masa molowa (HLiNaKRbCsBeMgCaSrBaScYLaTiZrAgAuZnCdHgBAlGaInCSiGeSnPbNPAs) = ∑ Counti * Weighti =
Count(H) * Weight(H) + Count(Li) * Weight(Li) + Count(Na) * Weight(Na) + Count(K) * Weight(K) + Count(Rb) * Weight(Rb) + Count(Cs) * Weight(Cs) + Count(Be) * Weight(Be) + Count(Mg) * Weight(Mg) + Count(Ca) * Weight(Ca) + Count(Sr) * Weight(Sr) + Count(Ba) * Weight(Ba) + Count(Sc) * Weight(Sc) + Count(Y) * Weight(Y) + Count(La) * Weight(La) + Count(Ti) * Weight(Ti) + Count(Zr) * Weight(Zr) + Count(Ag) * Weight(Ag) + Count(Au) * Weight(Au) + Count(Zn) * Weight(Zn) + Count(Cd) * Weight(Cd) + Count(Hg) * Weight(Hg) + Count(B) * Weight(B) + Count(Al) * Weight(Al) + Count(Ga) * Weight(Ga) + Count(In) * Weight(In) + Count(C) * Weight(C) + Count(Si) * Weight(Si) + Count(Ge) * Weight(Ge) + Count(Sn) * Weight(Sn) + Count(Pb) * Weight(Pb) + Count(N) * Weight(N) + Count(P) * Weight(P) + Count(As) * Weight(As) =
1 * 1.00794 + 1 * 6.941 + 1 * 22.98976928 + 1 * 39.0983 + 1 * 85.4678 + 1 * 132.9054519 + 1 * 9.012182 + 1 * 24.305 + 1 * 40.078 + 1 * 87.62 + 1 * 137.327 + 1 * 44.955912 + 1 * 88.90585 + 1 * 138.90547 + 1 * 47.867 + 1 * 91.224 + 1 * 107.8682 + 1 * 196.966569 + 1 * 65.38 + 1 * 112.411 + 1 * 200.59 + 1 * 10.811 + 1 * 26.9815386 + 1 * 69.723 + 1 * 114.818 + 1 * 12.0107 + 1 * 28.0855 + 1 * 72.64 + 1 * 118.71 + 1 * 207.2 + 1 * 14.0067 + 1 * 30.973762 + 1 * 74.9216 =
2462.7082 g/mol
