Hello student,

Raoult's Law :

The Raoult's law states that a solvent's partial vapour pressure in a solution or mixture is equal to the vapour pressure of a pure solvent multiplied by its mole fraction in the solution.

Mathematically, the law equation can be written as :

P _solution = Χ _solvent P ⁰ _{solvent, where...}

P _solution = vapour pressure of the solution
Χ _solvent = mole fraction of the solvent
P0 _solvent = vapour pressure of the pure solvent

Thank you and good luck!

Hello candidate,

Raoult's law state that the partial pressure of any individual component of a mixture is equal to the partial pressure of the pure solution multiplied with the mole fraction of that individual component.

For example- let the total pressure of the solution be (P), and the mole fraction of A equals to x, then the partial pressure of A= x*P.

Hope this information was helpful!!
