Given The fusion of deuterium and tritium produces
2.8×10−12J for every atom of deuterium
                                                                 Â
and 2.8×10−12J atom of tritium
We know that 1 mole of any compound contains avagadro number (
6.023x1023 atoms) of atoms.
So the energy produced for 1 mole=6.023x1023 atoms of
deuterium is
                                                                Â
= energy released per atom x 6.023x1023 atoms
                                                                Â
= 2.8×10−12x 6.023x1023 J
                                                                Â
= 1.7x1012 J
Therefore the energy produced per mole of deuterium and mole of
tritium is 1.7x1012 J
