How much energy is lost or gained when Co-60 undergoes between decay? Mass of Co-60 is 59.9338 amu, Mass of Ni-60 is 59.9308 amu. Look at the following reaction 238 92U 234 90Th + 42He What would be the energy released for the nuclear reaction above 238 92U = 238.0003 amu, 23490Th = 233.9942 amu and 42He = 4.0015 amu. What would be energy release if 1 Kg of 238U disintegrate to become 234 90Th + 42He. 1 amu=931.5 MeV,...
