Chapter 21, Problem 21.81QP

Interpretation Introduction

Interpretation:

The pressure of oxygen gas stored at given temperature which have the same density as the oxygen gas provided by ${\text{KO}}_{\text{2}}$ has to be calculated.

Concept introduction:

• First calculate the density of oxygen in ${\text{KO}}_{\text{2}}$ by using mass percentage of oxygen in the compound.
• Then, by using pressure and density relationship of the following formula calculate the pressure of oxygen provided by ${\text{KO}}_{\text{2}}$.

$\text{d = P}\mu \text{/RT}$
