Chapter 9, Problem 118QP

Interpretation Introduction

Interpretation:

The volume of $\text{NO}$ at STP is to be determined.

Concept Introduction:

Avogadro’s law gives a relationship at constant temperature and pressure between the volume of a gas and number of moles present in the gas. The volume of gas $\left(V\right)$ is directly proportional to the number of moles $\left(n\right)$ present in the gas at constant temperature and pressure.

$\begin{array}{l}V\propto n\\ \frac{V_1}{n_1}=\frac{V_2}{n_2}\end{array}$

Combined gas law is a law which is derived from the combination of Boyle’s law, Charles’ s law, and Gay-Lussac’s law. It states that the pressure $\left(P\right)$ and the volume $\left(V\right)$ of the gas are directly proportional to the temperature $\left(T\right)$ of the gas.

$\frac{P_1{V}_1}{T_1}=\frac{P_2{V}_2}{T_2}$ …(1)
