Consider the fission of $_{92}U^{238}$ by fast neutrons. In one fission event , no neutron are emitted and the final stable end products , after the beta decay of the primary fragments are $_{58}Ce ^{140}$ and $_{44}Ru ^{99}$ . Calculate Q for this fission process . The relevant atomic and particle masses are :$m(_92U^{238})=238.05079\;u$$m(_{34} Ru^{99}) = 98.90594\;u$$m(_{58}Ce^{140})=139.90543\;u$
