Find the amount of energy released when `1` atom of Uranium `._(92)U^(235)(235.0439 "amu")` undergoes fission by slow neturon `(1.0087 "amu")` and is splitted into Krypton `._(36)Kr^(92)(91.8973 "amu")` and Barium `._(56)Br^(141)(140.9139 "amu")` assuming no energy is lost. Hence find the enrgy in `kWh`, when `1g` of it undergoes fission.

Explanation

To solve the problem step by step, we will calculate the energy released during the fission of one atom of Uranium-235 and then find the total energy released when 1 gram of Uranium-235 undergoes fission.

### Step 1: Write the Fission Reaction
The fission of Uranium-235 by a neutron can be represented as follows:

\[ ^{235}_{92}U + ^1_0n \rightarrow ^{92}_{36}Kr + ^{141}_{56}Ba + \text{Energy} \]
