    In a mixture of volatile substances, the vapor pressure of the solution depends on the vapor pressure of both substances (solute and solvent). Each component can evaporate, but its vapor pressure is lowered by the presence of the other substance following Rault's law. The vapor pressure of the solvent is calculated using Psolvent = Xsolvent*Posolvent and the vapor pressure of the solute is calculated using Psolute = Xsolute*Posolute. The total vapor pressure can be calculated by Dalton's law of partial...
