The energy released per fission of nucleus of $\displaystyle { }^{240} \mathrm{X}$ is $\displaystyle 200$ MeV . The energy released if all the atoms in $\displaystyle 120$ g of pure $\displaystyle { }^{240} \mathrm{X}$ undergo fission is $\displaystyle \_\_\_\_$ $\displaystyle \times 10^{25} \mathrm{MeV}$. (Given $\displaystyle \mathrm{N}_{\mathrm{A}}=6 \times 10^{23}$ )
