Chapter 15, Problem 31CR

Interpretation Introduction

Interpretation:

The volume of ${\text{Cl}}_{\text{2}}$ gas at STP expected to produce when given amount of ${\text{MnO}}_{\text{2}}$ reacts with concentrated $\text{HCl}$ is to be calculated.

Concept Introduction:

Avogadro’s hypothesis states that at standard temperature and pressure, one mole of an ideal gas occupies $22.4\text{L}$ volume. The volume of a gas at STP is given as,

$\text{V}={\text{V}}_{\text{m}}\text{n}$

Where,

• ${\text{V}}_{\text{m}}$ is the molar volume of an ideal gas with value $22.4\text{L}\cdot {\text{mol}}^{-1}$.
• $\text{n}$ is the number of moles of an ideal gas.
