Question

In a fission reaction of U-235 there was a release of 9.20x1011kJ of energy. What amount of mass in grams would have been lost?
Recall that c = 3x108 m/s.Select one of the options below as your answer:
A. 1.02 x 10-2
B. 1.02 x 101C. 1.02 x 109
D. 8.28 x 10-2
E. 8.28 x 1022

Answer 1

The mass defect and energy released is associated in the formula expressed below:
E = delta m * c2 where c is the speed of light equal to 3x 10 ^8 m/s. Substituting, E equal to 9.20 x 1011 KJ, delta m is equivalent to 0.0102 kg. The answer hence is A.
