Chapter 13, Problem 13.82QP

(a)

Interpretation Introduction

Interpretation:

Total vapour pressure of given two liquids have 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 component

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

(b)

Interpretation Introduction

Interpretation:

Total vapour pressure of given two liquids have to be calculated.

(b)$\text{2}\text{.00 moles}$ of A and $\text{5}\text{.00 moles}$ of B
