Chapter 11, Problem 101E

Interpretation Introduction

Interpretation:

The ratio of nitrogen to oxygen is to be calculated.

Concept introduction: In ideal gas law, the volume of gas is directly proportional to the temperature of gas and number of moles and is inversely proportional to the pressure. The equation of ideal gas law is written as:

$PV=nRT$

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

The relation between moles of gas $\left(n\right)$ and mass $\left(m\right)$ is:

$n=\frac{m}{\text{Molar mass }}$
