$\displaystyle 0$ g of $\displaystyle \mathrm{NH}_3$ completely vapourises at $\displaystyle -33.42^{\circ} \mathrm{C}$ and $\displaystyle 1$ bar pressure and the enthalpy change in the process is $\displaystyle 23.4 \mathrm{~kJ} \mathrm{~mol}^{-1}$. The enthalpy change for the vapourisation of $\displaystyle 85$ g of $\displaystyle \mathrm{NH}_3$ under the same conditions is \_\_\_\_ kJ.
