Chapter 5, Problem 5.73QP

Interpretation Introduction

Interpretation:

The percent by volume of Oxygen gas in the mixture has to be calculated.

Concept Introduction:

• In a mixture of gases, every gas has anincomplete pressure which is the theoretical stressof that gas if it alone engaged the entire volume of the original combination at the same temperature.
• The sum pressure of an ideal gas mixture is the amount of the partial pressuresof the gases in the mixture.
• The pressure exerted by an individual gas in a mixture is known as itspartial pressure.
• Assuming we have a mixture of ideal gases, we can use the ideal gas law to solve problems involving gases in a mixture.
• Dalton's law of partial pressures states that the total pressure of a mixture of gases is equal to the sum of the partial pressures of the component gases:
• ${\text{P}}_{\text{Total}}\text{}{\text{=P}}_{\text{gas 1}}\text{}{\text{+P}}_{\text{gas 2}}\text{}{\text{+P}}_{\text{gas 3}}\text{}\mathrm{....}$
• A mole fraction is the unit less proportion of the number of moles of a mixture constituent and the total number of moles in the mixture.
• ${\text{χ}}_{\text{i}}\text{=}\frac{{\text{P}}_{\text{i}}}{{\text{P}}_{\text{total}}}$
