Question

In the fusion reaction $_1^2H+_1^2H→_2^3He+_0^1n$, the masses of deuteron, helium and neutron expressed in amu are 2.015, 3.017 and 1.009, respectively. If 1 kg of deuterium undergoes complete fusion, find the amount of total energy released. (1=amu 931.5 MeV).

• A. $9.0 \times 10^{13} \ J$
