Chapter 10, Problem 17RQ

Interpretation Introduction

Interpretation:

The mole fraction and the relation of the mole fraction with total pressure and partial pressure of a gas are to be explained.

Concept Introduction:

The pressure is the applied force per unit area. The mathematical expression of pressure is:

$P=\frac{F}{A}$

Here, $P$ is the pressure, $F$ is the force applied, and $A$ is the area. The SI unit of pressure is ${\text{N/m}}^2$(newton per meter square) or $\text{Pa}$(pascal).
