are molar heat of vaporization and heat of vaporization the same thing?
They can be but they may not be the same.
kJ/mol is one way of expression heat of vaporization but it may also be kJ/g, J/g, J/mol, kJ/kg, etc. It makes little different how it is expressed; the important thing is to keep the units straight in whatever calculations you are doing.
