A heavy nucleus P of mass number 240 and binding energy 7.6 MeV per nucleon splits in to two nuclei Q and R of mass numbers 110, 130 and binding energy per nucleon 8.5 MeV and 8.4 MeV, respectively. Calculate the energy released in the fission.
B.E. of heavy nucleus P
B.E. of heavy nucleus Q
B.E. of heavy nucleus R
Energy released
=[(935 + 1092) − 1824] MeV
= [2027 − 1824] MeV
= 203 MeV
