Question

The fusion of deuterium and tritium produces 2.8×10−12J for every atom of deuterium and atom of tritium. Part A How much energy is produced per mole of deuterium and mole of tritium. Express your answer using two significant figures.

Answer 1

Given The fusion of deuterium and tritium produces 2.8×10⁻¹²J for every atom of deuterium

                                                                   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

                                                                  = energy released per atom x 6.023x10²³ atoms

                                                                  = 2.8×10⁻¹²x 6.023x10²³ J

                                                                  = 1.7x10¹² J

Therefore the energy produced per mole of deuterium and mole of tritium is 1.7x10¹² J
