Najpierw oblicz liczbę każdego atomu w CuFeTcReRhPdAgWReOsIrPtAuHgOSPKUHFVCn20BLaAcPaSnSbClBrIYAtAs:
Cu: 1, Fe: 1, Tc: 1, Re: 2, Rh: 1, Pd: 1, Ag: 1, W: 1, Os: 1, Ir: 1, Pt: 1, Au: 1, Hg: 1, O: 1, S: 1, P: 1, K: 1, U: 1, H: 1, F: 1, V: 1, Cn: 20, B: 1, La: 1, Ac: 1, Pa: 1, Sn: 1, Sb: 1, Cl: 1, Br: 1, I: 1, Y: 1, At: 1, As: 1
Następnie wyszukaj masy atomowe każdego pierwiastka w układzie okresowym :
Cu: 63.546, Fe: 55.845, Tc: 96.906365, Re: 186.207, Rh: 102.9055, Pd: 106.42, Ag: 107.8682, W: 183.84, Os: 190.23, Ir: 192.217, Pt: 195.084, Au: 196.966569, Hg: 200.59, O: 15.9994, S: 32.065, P: 30.973762, K: 39.0983, U: 238.02891, H: 1.00794, F: 18.9984032, V: 50.9415, Cn: 285.17411, B: 10.811, La: 138.90547, Ac: 227.0277521, Pa: 231.03588, Sn: 118.71, Sb: 121.76, Cl: 35.453, Br: 79.904, I: 126.90447, Y: 88.90585, At: 209.987148, As: 74.9216
Teraz oblicz sumę iloczynów liczby atomów do masy atomowej:
Masa molowa (CuFeTcReRhPdAgWReOsIrPtAuHgOSPKUHFVCn20BLaAcPaSnSbClBrIYAtAs) = ∑ Counti * Weighti =
Count(Cu) * Weight(Cu) + Count(Fe) * Weight(Fe) + Count(Tc) * Weight(Tc) + Count(Re) * Weight(Re) + Count(Rh) * Weight(Rh) + Count(Pd) * Weight(Pd) + Count(Ag) * Weight(Ag) + Count(W) * Weight(W) + Count(Os) * Weight(Os) + Count(Ir) * Weight(Ir) + Count(Pt) * Weight(Pt) + Count(Au) * Weight(Au) + Count(Hg) * Weight(Hg) + Count(O) * Weight(O) + Count(S) * Weight(S) + Count(P) * Weight(P) + Count(K) * Weight(K) + Count(U) * Weight(U) + Count(H) * Weight(H) + Count(F) * Weight(F) + Count(V) * Weight(V) + Count(Cn) * Weight(Cn) + Count(B) * Weight(B) + Count(La) * Weight(La) + Count(Ac) * Weight(Ac) + Count(Pa) * Weight(Pa) + Count(Sn) * Weight(Sn) + Count(Sb) * Weight(Sb) + Count(Cl) * Weight(Cl) + Count(Br) * Weight(Br) + Count(I) * Weight(I) + Count(Y) * Weight(Y) + Count(At) * Weight(At) + Count(As) * Weight(As) =
1 * 63.546 + 1 * 55.845 + 1 * 96.906365 + 2 * 186.207 + 1 * 102.9055 + 1 * 106.42 + 1 * 107.8682 + 1 * 183.84 + 1 * 190.23 + 1 * 192.217 + 1 * 195.084 + 1 * 196.966569 + 1 * 200.59 + 1 * 15.9994 + 1 * 32.065 + 1 * 30.973762 + 1 * 39.0983 + 1 * 238.02891 + 1 * 1.00794 + 1 * 18.9984032 + 1 * 50.9415 + 20 * 285.17411 + 1 * 10.811 + 1 * 138.90547 + 1 * 227.0277521 + 1 * 231.03588 + 1 * 118.71 + 1 * 121.76 + 1 * 35.453 + 1 * 79.904 + 1 * 126.90447 + 1 * 88.90585 + 1 * 209.987148 + 1 * 74.9216 =
9659.7542 g/mol
