Explanation:
Detailed explanation-1: -Because, some particles of the initial nuclei are converted into energy, the mass of the final nuclei is less than the initial nuclei.
Detailed explanation-2: -The energy in MeV released due to conversion of 1 kg mass completely into energy is c=3×108 ms 1.
Detailed explanation-3: -When this mass disappears an equivalent amount of energy will be released. Hence when 1 amu disappears then the energy x MeV released is equal to 3.1096×10−6MeV.
