Chapter 13.5, Problem 13.5WE

Interpretation Introduction

Interpretation:

Vapour pressure of water over a solution has to be calculated.

Concept introduction:

Raoult’s law states that in an ideal mixture of liquid solution, partial pressure of every component is equal to its mole fraction multiplied into vapour pressure of its pure components.

${\text{P}}_{}{\text{= χ}}_{}{\text{P}}^{\text{°}}$

Where,

P- Partial pressure of each component

$\text{P°-}$ Partial pressure of its pure components

${\text{χ}}_{\text{1}}$- Mole fraction of the components
