Primero, calcula el número de cada átomo en HHeLiBeBNCScCaCoCuOFClNaNeCsUVWYAcEsSeZnPSAuArAlAmFmCmErReTm:
H: 1, He: 1, Li: 1, Be: 1, B: 1, N: 1, C: 1, Sc: 1, Ca: 1, Co: 1, Cu: 1, O: 1, F: 1, Cl: 1, Na: 1, Ne: 1, Cs: 1, U: 1, V: 1, W: 1, Y: 1, Ac: 1, Es: 1, Se: 1, Zn: 1, P: 1, S: 1, Au: 1, Ar: 1, Al: 1, Am: 1, Fm: 1, Cm: 1, Er: 1, Re: 1, Tm: 1
Luego, busque los pesos atómicos de cada elemento en la tabla periódica :
H: 1.00794, He: 4.002602, Li: 6.941, Be: 9.012182, B: 10.811, N: 14.0067, C: 12.0107, Sc: 44.955912, Ca: 40.078, Co: 58.933195, Cu: 63.546, O: 15.9994, F: 18.9984032, Cl: 35.453, Na: 22.98976928, Ne: 20.1797, Cs: 132.9054519, U: 238.02891, V: 50.9415, W: 183.84, Y: 88.90585, Ac: 227.0277521, Es: 252.08298, Se: 78.96, Zn: 65.38, P: 30.973762, S: 32.065, Au: 196.966569, Ar: 39.948, Al: 26.9815386, Am: 241.0568291, Fm: 257.095105, Cm: 243.0613891, Er: 167.259, Re: 186.207, Tm: 168.93421
Ahora, calcula la suma de los productos del número de átomos por el peso atómico:
Masa molar (HHeLiBeBNCScCaCoCuOFClNaNeCsUVWYAcEsSeZnPSAuArAlAmFmCmErReTm) = ∑ Counti * Weighti =

1 * 1.00794 + 1 * 4.002602 + 1 * 6.941 + 1 * 9.012182 + 1 * 10.811 + 1 * 14.0067 + 1 * 12.0107 + 1 * 44.955912 + 1 * 40.078 + 1 * 58.933195 + 1 * 63.546 + 1 * 15.9994 + 1 * 18.9984032 + 1 * 35.453 + 1 * 22.98976928 + 1 * 20.1797 + 1 * 132.9054519 + 1 * 238.02891 + 1 * 50.9415 + 1 * 183.84 + 1 * 88.90585 + 1 * 227.0277521 + 1 * 252.08298 + 1 * 78.96 + 1 * 65.38 + 1 * 30.973762 + 1 * 32.065 + 1 * 196.966569 + 1 * 39.948 + 1 * 26.9815386 + 1 * 241.0568291 + 1 * 257.095105 + 1 * 243.0613891 + 1 * 167.259 + 1 * 186.207 + 1 * 168.93421 =
