For example if your compound is water and you have the information the boiling point, Tb=(99.98 C), the enthalpy of vaporization= (40.65 kJ/mol) and the molar mass= 18.02g/mol. How do I get the units to cancel to find (degrees C/molality)?
This is the given equation also: Kb=(R(Tb^2)(molar mass))/ enthalpy of vaporization
