Weight loss during nuclear fission reaction

The nuclear fission energy for the isotope U-235 is 1.67x10^10 kJ/mole. What is the mass of the fission products produced from 1.000 kg of radioactive material U-235?
What is the percent weight loss?

Solution Preview

We have to remember, that unlike simple chemical reactions, nuclear fission reactions accompanying enormous energy release result in significant weight loss. The weight loss can be determined by the Einstein equation delta E = delta m x c^2, where delta E is the change of energy, delta m is the change of mass and c ...
