Boiling Point Elevation Calculator Calculate boiling point elevation — how much a dissolved solute raises a solvent's boiling point. Enter the solvent's boiling point, the ebullioscopic constant, molality, and van't Hoff factor to get the elevation and th — free online calculator.

Formula

i*Kb*m
  • Boiling Point Elevation Calculator calculates its result from van't Hoff factor, Ebullioscopic constant, Molality. It uses the formula i*Kb*m. Change any input to recalculate the result instantly.
  • The main inputs are van't Hoff factor, Ebullioscopic constant, Molality. Enter them in the units and format shown in the calculator.
  • Use the units, labels and assumptions shown beside each input so the formula is applied consistently.
  • Changing any input above recalculates the result with the same calculation engine used by this page.

Example: Boiling Point Elevation

Inputs
  • van't Hoff factor: 1
  • Ebullioscopic constant: 0.512
  • Molality: 1

Using van't Hoff factor = 1, Ebullioscopic constant = 0.512, Molality = 1, the calculated result is 0.512.
