Boiling point elevation coefficient can be calculated by the knowledge of it's heat of vaporization, boiling point and the molecular weight of the pure solvent. The calculated value then can be used to calculate the boiling point elevation by using this calculator : http://calistry.org/calculate/boilingPointElevation.
