1. The problem statement, all variables and given/known data
In a nuclear reactor, each atom of uranium (235 amu) releases about 200 MeV when it fissions. What is the change in mass when 1.0 kg of uranium 235 is fissioned?
2. Relevant equations
E = mc2
3. The attempt at a solution
I found the energy released per kg based on the numbers above, plugged it in to the above formula and got a number I do not think is reasonable: 9.11 x 10-10. That number reminds me of the mass of an electron, only its orders of magnitude higher. Am I oversimplifying this problem? It really has me confused. Thanks in advance,
Lee
