먼저 HHeLiBeCBONFNeNaMgSiAlClSPBrIAsUPuKCsRbFrRaRnKr에 있는 각 원자의 수를 계산합니다.
H: 1, He: 1, Li: 1, Be: 1, C: 1, B: 1, O: 1, N: 1, F: 1, Ne: 1, Na: 1, Mg: 1, Si: 1, Al: 1, Cl: 1, S: 1, P: 1, Br: 1, I: 1, As: 1, U: 1, Pu: 1, K: 1, Cs: 1, Rb: 1, Fr: 1, Ra: 1, Rn: 1, Kr: 1
그런 다음 주기율표 의 각 원소에 대한 원자량을 검색합니다.
H: 1.00794, He: 4.002602, Li: 6.941, Be: 9.012182, C: 12.0107, B: 10.811, O: 15.9994, N: 14.0067, F: 18.9984032, Ne: 20.1797, Na: 22.98976928, Mg: 24.305, Si: 28.0855, Al: 26.9815386, Cl: 35.453, S: 32.065, P: 30.973762, Br: 79.904, I: 126.90447, As: 74.9216, U: 238.02891, Pu: 238.0495599, K: 39.0983, Cs: 132.9054519, Rb: 85.4678, Fr: 223.0197359, Ra: 226.0254098, Rn: 210.990601, Kr: 83.798
이제 원자 수와 원자량의 곱의 합을 계산합니다.
