Chapter 21, Problem 21.32QP

Interpretation Introduction

Interpretation:

The volume of ${\text{CO}}_{\text{2}}$ at a given temperature and pressure obtained by treating ${\text{Na}}_{\text{2}}{\text{CO}}_{\text{3}}$ with an excess of hydrochloric acid has to be calculated.

Concept introduction:

• First write the balanced reaction for the given starting material and product.
• Then, calculate the mol value of ${\text{CO}}_{\text{2}}$ from the given mass of ${\text{Na}}_{\text{2}}{\text{CO}}_{\text{3}}$.
• Finally, from the mol value of ${\text{CO}}_{\text{2}}$ we can calculate the volume of ${\text{CO}}_{\text{2}}$ at given temperature and the pressure by using volume calculation formula.

• The formula for volume calculation: $\text{V=}\frac{\text{nRT}}{\text{P}}$

To determine: The volume of ${\text{CO}}_{\text{2}}$ at given ${\text{10}}^{\text{o}}\text{C}$ temperature and 746 mmHg pressure.
