The fission properties of $_{84}Pu^{237}$ are similar to those of $_{92} U^{35}$ . The average energy released per fission is $180\;Mev$ How much energy in Mev is released if all the atoms in 1 kg of pure $_{94} Pu ^{239}$ undergo fission .

Question

$\begin{array}{1 1} 4.53 \times 10^{25}\;Mev \\ 4.53 \times 10^{24}\;Mev \\ 4.53 \times 10^{26}\;Mev \\ 4.53 \times 10^{27}\;Mev \end{array}$
