The fusion of deuterium and tritium produces 2.8 × 10−12 J for every atom of deuterium and atom of tritium. How much energy is produced per mole of deuterium and mole of tritium?

Solution 92P :

Step 1 :

Given :

Energy produced per atom in fusion of deuterium and tritium = 2.8 × 10-12 J

Energy produced per mole of deuterium and mole of tritium = ?

We calculate energy produced per mole using Einstein’s energy equation :

E = mc2

where, E = energy

m = mass converted to energy

c = velocity of light = 3108 m/s

Before calculating energy per mole , we need to know the mass of deuterium and tritium in the fusion reaction :

Formula to find mass becomes :

m =

m =

= 3.1110-29 Kg
