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.
