1A. Vapor Pressure Lowering
How much a dissolved solute lowers the vapor pressure of a solvent depends on the solute
concentration and is expressed by Raoult's Law which states that the vapor pressure of a component in
a solution depends on its mole fraction times the vapor pressure exerted by the pure component:
Psolution = (Xsolvent) (Psolvent)
where:
Psol'n = vapor pressure of the solution caused by the solvent
Xsolv = mole fraction of solvent in the solution
Psolv = vapor pressure of pure solvent at the same temperature
Note: pressure must be expressed in Torr (1 torr = 1 mmHg)
