Question

In a fission reaction of U-235, there was a release of 9.20 × 1011 kJ of energy. What amount of mass in kilograms would have been lost? Recall that c = 3 × 108 m/s.

1.02 × 10-2
1.02 × 10-5
1.02 × 109
8.28 × 10-2
8.28 × 1022

Answer 1

e = mc^2

m = e / c^2

Plug in your numbers in the appropriate units.
m=1.02 × 10^-5
