At 298 K , the enthalpy of fusion of a solid X is 2 . 8 kJ mol - 1 and the enthalpy of vaporisation of the liquid X is 98 . 2 kJ mol - 1 . The enthalpy of sublimation of the substance X in kJ mol - 1 is ______. (in nearest integer)

Correct answer

0

Step-by-step solution

ΔH sub = ΔH fus . + ΔH vap . = 2 . 8 + 98 . 2 = 101   kJ / mol
