Boiling point elevation (the boiling point goes up) occurs when solute is added to the pure solvent. Thus the amount of elevation depends on the amount of solute added into the solution, i.e depends on the molarity (M) of the solution. Thus by the knowledge of the "Boiling Point Elevation Coefficient" one can easily obtain the boiling point elevation of the component ( i.e the solvent). To calculate the "Boiling Point Elevation Coefficient" use this calculator: http://calistry.org/calculate/boilingPointElevationCoeff
