The expression for
Concept introduction:
According to the Raoult’s law, the vapor pressure of the solution is equal to the product of vapor pressure of the solvent and its mole fraction in the solution.
According to the Dalton’s law of gases, the partial pressure of a component is equal to the product of total pressure of the gas mixture and mole fraction of that component.
