A heavy nucleus X of mass no. 240 and binding energy per nucleon is 7.6 Mev is split into Y and Z of mass no. 110 and 130. the binding energy of nucleons in Y & Z is 8.5 Mev per nucleon. calculate the energy released per fission in Mev.
Energy released per nucleon = (8.5 - 7.6) MeV = 0.9 MeV
Therefore energy released = 0.9 x 240 MeV = 216 MeV
