Raoult's law for a solution containing volatile components states that the partial pressure of a volatile component present in a solution is directly proportional to the mole fraction of that component at a given temperature.

Raoult's law and Henry's law are similar as both gives equation to find partial pressure of gases.
${\mathrm{P}}_{\mathrm{A}}=\mathrm{K}{\mathit{\chi }}_{\mathrm{A}}{\mathrm{P}}_{\mathrm{A}}={\mathrm{K}}_{\mathrm{H}}{\mathit{\chi }}_{\mathrm{A}}$
