What is the Raoults Law exactly? What is it's statement ?

It states that for an ideal solution,the partial vapour pressure of a component is equal to the mole fraction of the component times the partial vapour pressureof the component when pure.

Pa= mole fraction x pressure of the pure solvent

The partial vapor pressure of each component of an ideal mixture of liquids is equal to the vapor pressure of the pure component multiplied by its mole fraction in the mixture. The total vapor pressure of the ideal solution is then directly dependent on the vapor pressure of each chemical component and the mole fraction of the component present in the solution.
