Solution:
Energy released in one fission of
‌ 92 235 U nucleus
= 200 M e V Mass of uranium
= 1 g We know that,
235 g of
‌ 235 U has
6.023 × 10 23 atoms or nuclei.
∴ Energy released in fission of
1 g of
U 235 ,
E ‌ ‌ = ‌ ‌ ‌ = 5.1 × 10 23 M e V ‌ ‌ = 5.1 × 10 23 × 1.6 × 10 − 13 J = ‌ 5.1 × 10 23 × 16 × 10 − 13 3.6 × 10 6
