Mohon bantuannya ya teman temann defek massa untuk inti 6Li adalah -0,03434 g/mol. hitunglah massa atom 6Li

∆m = -0,03434
Z (nomor atom) = 3
mp = 1,007825 sma
mn = 1,00865
n = A - Z = 3
m inti = ?

∆m = {Z . mp + (A-Z) mn} - m inti
-0,03434 = {3×1,007825 + (3-3)×1,00865} - m inti
-0,03434 = (3,023475) - m inti
- m inti = -0,03434 - 3,023475
- m inti = −3.057815
m inti = 3,057815 sma
