Acetic acid has a heat of fusion of 10.8 kJ/mol and a heat of vaporization of 24.3 kJ/mol. What is the expected value for the heat of sublimation of acetic acid?

Heat of sublimation = heat of fusion + heat of vaporization = 10.8 + 24.3 = 35.1 kJ/mol
Heat of sublimation = heat of fusion + heat of sublimation = 10.8 + 24.3 = 35.1 kJ/mol
