Instead of allowing 1 kg of U-235 to decay naturally, imagine it is used as fuel in a nuclear reactor. It is bombarded with neutrons, causing it all to fission in a matter of days. After 1 kg of U-235 undergoes fission, the mass of the products is [tex]8.4 \times 10^{-4}[/tex] kg less than the initial 1 kg.

How much energy was produced by the fission of 1 kg of U-235?

(Hint: Use Einstein's equation, [tex]E = mc^2[/tex], where E is energy in Joules, m is mass in kilograms, and c is the speed of light, [tex]3 \times 10^8[/tex] m/s.)

Answer :

Answer:

The Uranium loses 8.4 x 10^-4kg. Plug this into the equation E = mc^2 and that is the answer.

Explanation:

Hopefully that helps a little. Im also trying to solve this question.
