If ^235U (235.043930 u) is struck by a neutron it undergoes fission producing ^144 Ba (143.922953 u), ^89 Kr (88.917630 u) and three neutrons (1.0086649 u).
(a) Calculate the energy in MeV released by each fission reaction.
(b) Calculate the energy released per gram of ^235U in MeV/g.
I will be happy to critique your thinking. Find the change of mass from the reactants to products.
