Najpierw oblicz liczbę każdego atomu w BaBeAuAgArRnTiUWHOCCaClCrBBrMnMgYIInAlSeAsGeGaNaNNeFeScNiFP:
Ba: 1, Be: 1, Au: 1, Ag: 1, Ar: 1, Rn: 1, Ti: 1, U: 1, W: 1, H: 1, O: 1, C: 1, Ca: 1, Cl: 1, Cr: 1, B: 1, Br: 1, Mn: 1, Mg: 1, Y: 1, I: 1, In: 1, Al: 1, Se: 1, As: 1, Ge: 1, Ga: 1, Na: 1, N: 1, Ne: 1, Fe: 1, Sc: 1, Ni: 1, F: 1, P: 1
Następnie wyszukaj masy atomowe każdego pierwiastka w układzie okresowym :
Ba: 137.327, Be: 9.012182, Au: 196.966569, Ag: 107.8682, Ar: 39.948, Rn: 210.990601, Ti: 47.867, U: 238.02891, W: 183.84, H: 1.00794, O: 15.9994, C: 12.0107, Ca: 40.078, Cl: 35.453, Cr: 51.9961, B: 10.811, Br: 79.904, Mn: 54.938045, Mg: 24.305, Y: 88.90585, I: 126.90447, In: 114.818, Al: 26.9815386, Se: 78.96, As: 74.9216, Ge: 72.64, Ga: 69.723, Na: 22.98976928, N: 14.0067, Ne: 20.1797, Fe: 55.845, Sc: 44.955912, Ni: 58.6934, F: 18.9984032, P: 30.973762
Teraz oblicz sumę iloczynów liczby atomów do masy atomowej:
Masa molowa (BaBeAuAgArRnTiUWHOCCaClCrBBrMnMgYIInAlSeAsGeGaNaNNeFeScNiFP) = ∑ Counti * Weighti =
Count(Ba) * Weight(Ba) + Count(Be) * Weight(Be) + Count(Au) * Weight(Au) + Count(Ag) * Weight(Ag) + Count(Ar) * Weight(Ar) + Count(Rn) * Weight(Rn) + Count(Ti) * Weight(Ti) + Count(U) * Weight(U) + Count(W) * Weight(W) + Count(H) * Weight(H) + Count(O) * Weight(O) + Count(C) * Weight(C) + Count(Ca) * Weight(Ca) + Count(Cl) * Weight(Cl) + Count(Cr) * Weight(Cr) + Count(B) * Weight(B) + Count(Br) * Weight(Br) + Count(Mn) * Weight(Mn) + Count(Mg) * Weight(Mg) + Count(Y) * Weight(Y) + Count(I) * Weight(I) + Count(In) * Weight(In) + Count(Al) * Weight(Al) + Count(Se) * Weight(Se) + Count(As) * Weight(As) + Count(Ge) * Weight(Ge) + Count(Ga) * Weight(Ga) + Count(Na) * Weight(Na) + Count(N) * Weight(N) + Count(Ne) * Weight(Ne) + Count(Fe) * Weight(Fe) + Count(Sc) * Weight(Sc) + Count(Ni) * Weight(Ni) + Count(F) * Weight(F) + Count(P) * Weight(P) =
1 * 137.327 + 1 * 9.012182 + 1 * 196.966569 + 1 * 107.8682 + 1 * 39.948 + 1 * 210.990601 + 1 * 47.867 + 1 * 238.02891 + 1 * 183.84 + 1 * 1.00794 + 1 * 15.9994 + 1 * 12.0107 + 1 * 40.078 + 1 * 35.453 + 1 * 51.9961 + 1 * 10.811 + 1 * 79.904 + 1 * 54.938045 + 1 * 24.305 + 1 * 88.90585 + 1 * 126.90447 + 1 * 114.818 + 1 * 26.9815386 + 1 * 78.96 + 1 * 74.9216 + 1 * 72.64 + 1 * 69.723 + 1 * 22.98976928 + 1 * 14.0067 + 1 * 20.1797 + 1 * 55.845 + 1 * 44.955912 + 1 * 58.6934 + 1 * 18.9984032 + 1 * 30.973762 =
2418.8488 g/mol
