Chapter 12, Problem 36PE

Interpretation Introduction

Interpretation:

Molecules of ${\text{CO}}_2$ gas present in $10.5\text{ L}$ at STP have to be determined.

Concept Introduction:

Density of gas represents mass of gas present in unit volume. Expression of density is as follows:

  $d\left(\text{g/L}\right)=\frac{\text{mass}\left(\text{g}\right)}{\text{volume}\left(\text{L}\right)}$

Here, $d$ is density of gas.

Conversion factor for conversion of $\text{mol}$ to $\text{L}$ at STP is as follows:

  $\left(\frac{22.4\text{ L}}{1\text{ mol}}\right)$
