Chapter 19, Problem 19.6E

Interpretation Introduction

Interpretation:

The average velocity of the argon atoms in a sample of $0.44\text{0 mol}$ of $\text{Ar}$ gas is to be calculated.

Concept introduction:

According to the kinetic theory of gases, there are large numbers of identical particles that are present in gases. These particles are tiny and very far from each other. The volume occupied by the gaseous molecules is almost negligible in comparison of the space that is present between the particles. Therefore, gases are highly compressible. In kinetic theory, the pressure of an ideal gas is given by an expression,

$P=\frac{N\cdot m\cdot v_{\text{avg}}^2}{3V}$
