What is the nuclear binding energy of N-14 in joules per mole of nuclei? The mass deficit is 0.11278. Atomic mass is 14.00307. Total mass is 14.11585. I keep getting stuck after converting and substituting it into the equation. First I converted the mass deficit into kilograms. 0.11278 =1.1278 × 10^-1KG. Then I put into equation. E=mc2=1.1278 × 10^-1 kgmol × (2.998×108ms)^2 . I am not quite sure if this is right so far or what to do next. Any help is greatly appreciated. Thanks!
