The explosive in a hydrogen bomb is a mixture of 1 H 2 , 1 H 3 and 3 Li 6 in some condensed form. The chain reaction is given by 3 Li 6 + 0 n 1 → 2 He 4 + 1 H 3 1 H 2 + 1 H 3 → 2 He 4 + 0 n 1 During the explosion the energy released is approximately [Given : M(Li) = 6.01690 amu, M( 1 H 2 ) = 2.01471 amu, M( 2 He 4 ) = 4.00388 amu, and 1 amu = 931.5 MeV]

1. 22.22 MeV
2. 16.48 MeV
3. 28.12 MeV
4. 12.64 MeV

Correct answer: 22.22 MeV
