Vapor Pressure Calculator (Solvent/Solution)

Enter the mole fraction and vapor pressure of a solvent into the calculator below to calculate the vapor pressure of the solution.

Vapor Pressure Formula

The following formula is used to calculate the vapor pressure of a solvent.

VP(solution) = MF * VP(solvent)

  • Where VP(solution) is the the vapor pressure of the solution
  • MF is the mole fraction
  • VP(solvent) is the vapor pressure of the solvent.

This equation is also known as Raoult’s Law. A law that describes the change in vapor pressure of a solution based on mole fractions and pressures of the solvent.
