Chapter 10, Problem 42QP

Interpretation Introduction

Interpretation:

The volume of gas at STP is to be determined.

Concept introduction:

The ideal gas equation is represented below:

$PV=n\text{R}T.$

Here, R is the gas constant, $P$ is the pressure, $V$ is the volume, $n$ is the number of moles, and $T$ is the temperature.

When the number of moles of gas is constant, $\frac{PV}{\text{R}T}$ is constant as well.

Therefore, for the gas, $\frac{P_1{V}_1}{T_1}=\frac{P_2{V}_2}{T_2}.$
