Deuterium fuses with tritium by the following reaction: 21H 31H⟶42He 10n.The atomic masses of deuterium and tritium are 2.014102u and 3.016049u respectively. Calculate the energy in joules released by the fusion of a 1.25 -kg mixture of deuterium and tritium, which produces helium. There are equal numbers of deuterium and tritium nuclei in the mixture.
