Chapter 13, Problem 13.139SP

Interpretation Introduction

Interpretation:

The composition of the given solution needs to be determined in terms of mass percent.

Concept introduction:

The relation between partial pressure, mole fraction and pressure of pure component is represented as follows:

$P_A={\chi }_A{P}_A^o$

Here, $P_A$ is partial pressure of component A in solution, ${\chi }_A$ is mole fraction of component A and $P_A^o$ is pressure of pure component.

Total pressure is sum of partial pressure of two components in the mixture say A and B:

$P_T=P_A+P_B$
