Primero, calcula el número de cada átomo en HDBCNOFPSKVYIWULaCePrNdPmTcSmNpPuAmCmCnRgNaLiRuRhAgAuHgTlPb:
H: 1, B: 1, C: 1, N: 1, O: 1, F: 1, P: 1, S: 1, K: 1, V: 1, Y: 1, I: 1, W: 1, U: 1, La: 1, Ce: 1, Pr: 1, Nd: 1, Pm: 1, Tc: 1, Sm: 1, Np: 1, Pu: 1, Am: 1, Cm: 1, Cn: 1, Rg: 1, Na: 1, Li: 1, Ru: 1, Rh: 1, Ag: 1, Au: 1, Hg: 1, Tl: 1, Pb: 1, D: 1
Luego, busque los pesos atómicos de cada elemento en la tabla periódica :
H: 1.00794, B: 10.811, C: 12.0107, N: 14.0067, O: 15.9994, F: 18.9984032, P: 30.973762, S: 32.065, K: 39.0983, V: 50.9415, Y: 88.90585, I: 126.90447, W: 183.84, U: 238.02891, La: 138.90547, Ce: 140.116, Pr: 140.90765, Nd: 144.242, Pm: 144.912749, Tc: 96.906365, Sm: 150.36, Np: 236.04657, Pu: 238.0495599, Am: 241.0568291, Cm: 243.0613891, Cn: 285.17411, Rg: 280.16447, Na: 22.98976928, Li: 6.941, Ru: 101.07, Rh: 102.9055, Ag: 107.8682, Au: 196.966569, Hg: 200.59, Tl: 204.3833, Pb: 207.2, D: 2.0141017778
Ahora, calcula la suma de los productos del número de átomos por el peso atómico:
Masa molar (HDBCNOFPSKVYIWULaCePrNdPmTcSmNpPuAmCmCnRgNaLiRuRhAgAuHgTlPb) = ∑ Counti * Weighti =

1 * 1.00794 + 1 * 10.811 + 1 * 12.0107 + 1 * 14.0067 + 1 * 15.9994 + 1 * 18.9984032 + 1 * 30.973762 + 1 * 32.065 + 1 * 39.0983 + 1 * 50.9415 + 1 * 88.90585 + 1 * 126.90447 + 1 * 183.84 + 1 * 238.02891 + 1 * 138.90547 + 1 * 140.116 + 1 * 140.90765 + 1 * 144.242 + 1 * 144.912749 + 1 * 96.906365 + 1 * 150.36 + 1 * 236.04657 + 1 * 238.0495599 + 1 * 241.0568291 + 1 * 243.0613891 + 1 * 285.17411 + 1 * 280.16447 + 1 * 22.98976928 + 1 * 6.941 + 1 * 101.07 + 1 * 102.9055 + 1 * 107.8682 + 1 * 196.966569 + 1 * 200.59 + 1 * 204.3833 + 1 * 207.2 + 1 * 2.0141017778 =
