The Amount of Energy Released by the Neutron Induced Fission ${ } ^ { 235 } \mathrm { U }$

The amount of energy released by the neutron induced fission of ${ } ^ { 235 } \mathrm { U }$ to give ${ } ^ { 90 } \mathrm { Sr }$ , ${ } ^ { 143 } \mathrm { Xe }$ , and three neutrons is _____ MeV/atom. (Given, the experimentally determined mass of ${ } ^ { 235 } \mathrm { U }$ = 235.043930 amu, ${ } ^ { 90 } \mathrm { Sr }$ = 89.907738 amu, ${ } ^ { 143 } \mathrm { Xe }$ = 142.935110 amu, and mass of neutron = 1.008665 amu)
