Expert Solution
Step 1

Given that:∆E=200 MeV=200×1.6×10-13=3.2×10-11 JTotal mass, M=1.00 kgAtomic mass, MA=235 u1u=1.66×10-27 kg

Reflection of problem:

You need to find change in mass for each atom. Then total number of atoms in 1 kg. Hence we can find total change in mass for 1 kg fission of Uranium.
