How much energy is liberated by-
(i) the fission of 1 g of U 235 , assuming an energy of 200 MeV for each fission process
(ii) the fusion of 1 g of the mixture H 2 + H 3 ? Given,
Avogadro’s number = 6.023 × 10 23
Mass of 1 H 2 = 2.014740 mass unit
Mass of 1 H 3 = 3.017005 mass unit
Mass of neutron = 1.008986 mass unit
Mass of 2 He 4 = 4.003874 mass unit
