Raoult's Law

Raoult's law is the vapor pressure of a solution is changed by the addition of a solute.

 

formulas that use Raoult's Law

\(\large{ p_s = x_s\; p°_s  }\)

Where:

\(\large{ p_s }\) = vapor pressure of the solution

\(\large{ x_s }\) = mole fraction of the solvent in the solution

\(\large{ p°_s }\) = vapor pressure of the pure solvent at standard conditions
