Chapter 9, Problem 128QP

Interpretation Introduction

Interpretation:

The mass of sodium azide needed to fill $\text{2}\text{.50 L}$ air bag with nitrogen gas is to be determined.

Concept Introduction:

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

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