Raoult's Law

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

 

Raoult's Law Formula

\(\large{ p_s = x_s\; p°_s  }\)

Where:

Units	English	Metric
\(\large{ p_s }\) = vapor pressure of the solution	\(\large{\frac{lbf}{in^2}}\)	\(\large{Pa}\)
\(\large{ x_s }\) = mole fraction of the solvent in the solution	\(\large{dimensionless}\)
\(\large{ p°_s }\) = vapor pressure of the pure solvent at standard conditions	\(\large{\frac{lbf}{in^2}}\)	\(\large{Pa}\)
