Question

The fission properties of are very similar to those of.

The average energy released per fission is 180 MeV. How much energy, in MeV, is released if all the atoms in 1 kg of pure undergo fission?

Solution

Average energy released per fission of,

Amount of pure, m = 1 kg = 1000 g

NA= Avogadro number = 6.023 × 1023

Mass number of= 239 g

1 mole of contains NA atoms.

m g of contains

Total energy released during the fission of 1 kg ofis calculated as:

Hence, is released if all the atoms in 1 kg of pure undergo fission.
