Calculate and compare the energy released by (a) Fusion of 1.0 kg of hydrogen deep within Sun (b) The fission of 1.0 kg of in a fission reactor

Solution: A. 
Amount of hydrogen,
1 mole, i.e.e , 1 g of hydrogen contains atoms. Therefore 1000 g of hydrogen contains atoms. 
Within the Sun, four nuclei combine and form one  nucleus. In this process of energy is released. Hence the energy released from fusion of is 

B: 

Amount of = 1 kg = 1000 g 
One mole i.e. 235 g of contains atoms. Therefore 1000 g of  contains atoms.

It is known that the amount of energy released in the fission of one atom of is

Hence, energy released from the fission of 1 kg of is 
Therefore, the energy released in the fusion of 1 kg of hydrogen is nearly 8 times the energy released in the fission of one kg of uranium.
