Interpretation Introduction

Interpretation:

The mass of sodium aziderequired to fill the $125\text{ L}$ air bag at85°Cand $1\text{ atm}$ is to be calculated.

Concept introduction:

The ideal gas equation elaborates the physical properties of gases by relating the pressure, volume, temperature, and the number of moles with each other with the help of gas laws.

This can be shown by:

$P=\frac{nRT}{V}$

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

Number of moles is defined as the ratio of the mass to the molar mass.

$n=\frac{m}{M}$

Here, $n$ is the number of moles, $m$ is the mass, and $M$ is the molar mass.
