You could calculate the molar heat of sublimation as long as you know by placing a known amount of a known quantity in a calorimeter and measuring the change in temperature during sublimation. Then use the equation E=mc(change in T) where E is energy in joules, m is mass, c is heat capacity, and T is temperature.

The molar heats of sublimation and fusion of iodine are 62.3kjmol and 15.3kjmol respectively calculate the molar heat of vaporization of liquid iodide?
It is a known fact : Molar heat of sublimation = molar heat of fusion + molar heat of vaporization so, molar heat of vaporization = molar heat of sublimation - molar heat of fusion Mv = 62.3 kJ/mol - 15.3 kJ/mol Mv = 47 kJ/mol.
What is the difference between heat of reaction and molar heat of reaction?
Heat of a reacion is the totall amount of heat a reaction produces. Molar heat of a reaction is the heat produced/mol if you have the molar hear of the reaction you can calculate the heat of the reaction based on the moles of reactants you have
What is the molar heat of combustion of 1-octanol?
The molar heat of combustion of octanol is 5294
When 1 gram of zinc chloride ZnCl2 is dissolved in water the heat evolved is 0.53kJ Calculate the molar heat of substance of solution of zinc chloride?
-40.1 KJ/mol
What is molar heat?
Different substances have varied molar heat capacities. The molar heat capacity of a substance refers to the amount of heat energy needed to raise 1 mole of that substance by 1 degree Celsius.

How do you calculate the molar heat of fusion?
Use Einstein's Theory of Special Relativity
Is heat taken away or added in sublimation?
Sublimation is an endothermic physical change (heat is needed).
What is the specific heat of an unknown substance if 2000 j of energy are required to raise the temperature of 4 grams of the substances 5 degrees celsius?
You cannot calculate the specific heat without knowing the molar mass of the substance in question. Units of specific heat are given in joules/mol, with no reference to molar mass there is no way to calculate the number of moles of substance being heated.
What is the molar heat of combustion of 1-octanol?
The molar heat of combustion of octanol is 5294
What are affected by an increase in intermolecular forces?
Capillary attraction, Melting point, Heat of vaporization Sublimation temperature, Surface tension, Vapor pressure, Heat of fusion Boiling point, Viscosity, Density, Heat of sublimation Apex: Boiling point, viscosity, heat of sublimation, density.

Molar heat capacity of water?
Molar heat capacity of liquid water = 75.3538 Molar heat capacity = molar mass x specific heat
What is the experimental molar heat of combustion?
The experimental molar heat of combustion is the heat released by the total combustion of a substance, determined in a calorimeter.
What is the heat of sublimation of Sodium at stp?
108kJ/mol
