Chapter 12, Problem 12.150CP

Interpretation Introduction

Interpretation:

Composition of the solution in mass percent should be determined.

Concept introduction:

According to the Raoult’s Law, for volatile liquids, the vapor pressure of the componentof the given temperature is equal to the mole fraction of the component present in the solution multiplied by the vapor pressure the component in the pure state.
${\text{P}}_{\text{soln}}{\text{ = P}}_{\text{solv}}\times {\text{ X}}_{\text{solv}}$

Here, ${\text{P}}_{\text{soln}}$ = vapor pressure of the solution

;${\text{P}}_{\text{solv}}$ = vapor pressure of the pure solvent

${\text{X}}_{\text{solv}}$ = mole fraction of solvent at the given temperature.
