Problem 91P

The fission of U-235 produces 3.2 × 10−11J/atom. How much energy does it produce per mole of U-235? Per kilogram of U-235?

Step-by-Step Solution:

Solution 91P :

Step 1:

Given :

Energy produced in fission of  U-235 = 3.2 × 10-11 J/atom

Energy produced per mole of U-235 = ?

Energy produced per Kg of U-235 = ?

Before calculating energy per mole, we need to know the mass of Uranium in the fission reaction. So let’s calculate the mass from Einstein's famous equation:

E = mc2

where, E = energy

m = mass converted to energy

c = velocity of light = 3108 m/s

Formula to find mass becomes :

m =

m =

= 3.5510-28 Kg

Step 2:

Now, that we know the mass of Uranium that was used in the fission reaction, let’s calculate the energy released per mole :

We know, 1 mole of any particle contains avogadro’s number of particles(6.0231023 particles)

E = 3.5510-28 Kg (3108 m/s)2  6.0231023

= 1.9 × 1013 joules.

Hence the energy produced per mole in the fission reaction of U-235 is 1.9 × 1013 joules.
