Answer:
Correct Answer: 3.(c)
Solution:
(c) 1 atom of ${ } _{92}^{235} \mathrm{U}$ on fission gives energy
$ =3.2 \times 10^{-11} \mathrm{~J} $
$6.023 \times 10^{23}$ atom ( 1 mole) on fission gives energy
$ =3.2 \times 10^{-11} \times 6.023 \times 10^{23} \mathrm{~J} $
$1 \mathrm{~g}$ of ${ } _{92}^{235} \mathrm{U}$ on fission gives energy
$ =\frac{6.023}{235} \times 3.2 \times 10^{12} \mathrm{~J}=8.2 \times 10^7 \mathrm{~kJ} $
