Interpretation Introduction

Interpretation:

The number of molecules of $\text{1}\text{.12 L}$ of ${\text{CO}}_2$ gas at $\text{STP}$ dissolved in $\text{75}\text{.0 mL}$ of aqueous solution, is to be stated.

Concept introduction:

The number of molecules of any gas present at $\text{STP}$ is always $6.022\times {\text{10}}^{\text{23}}\text{ molecules}$. This number is also known as avagadro’ number. Number of molecules present is also dependent upon the volume, pressure and tempearture of the gas.
