Chapter 6, Problem 6.143QP

(a)

Interpretation Introduction

Interpretation: The mass of a gas, temperature and volume of the container is given. The pressure exerted by the gas is to be calculated for both the condition that the gas behaves as non-ideally and ideally.

Concept introduction: The van der Waals equation is given by the formula,

$\left(P+\frac{n^{2}a}{V^2}\right)\left(V-nb\right)=nRT$

The ideal gas equation is given by the formula,

$PV=nRT$

Where,

• $P$ is the pressure exerted by the gas.
• $\frac{n^{2}a}{V^2}$ is the pressure corrected term.
• $V$ is the volume of the container.
• $nb$ is the volume corrected term.
• $n$ is the number of moles.
• $R$ is the universal gas constant.
• $T$ is the temperature of the system.

To determine: The pressure exerted by hydrogen gas if for the non-ideal behaviour using van der Waals equation.
