At 298 K , the enthalpy of fusion of a solid $(\mathrm{X})$ is $2.8 \mathrm{~kJ} \mathrm{~mol}^{-1}$ and the enthalpy of vaporisation of the liquid $(\mathrm{X})$ is $98.2 \mathrm{~kJ} \mathrm{~mol}^{-1}$. The enthalpy of sublimation of the substance $(\mathrm{X})$ in $\mathrm{kJ} \mathrm{mol}^{-1}$ is $\_\_\_\_$ (in nearest integer)
