Explanation / Answer

Amount of hydrogen = 5kg

1g of hydrogen contains 6.023×10^23atoms

So 5000g contains = 5000× 6.023×10^23 atoms

With in sun four hydrogen combine to form helium in this process 26Mev energy released

Hence energy released by 5kg of hydrogen = 5000×26×6.023×10^23/4=195.7475×10^26Mev

B) 235 g of u235 contains 6.023×10^23atoms

5000g of u235 contains 6.023×10^23×5000/235 atoms

Energy released by 1atom of uranium = 200Mev

So energy released by 5kg of uranium = 5000×6.023×10^23/235=25.53×10^26Mev
