Chapter 8, Problem 6QRT

Interpretation Introduction

Interpretation:

Dalton’s Law has to be stated. Partial pressure and mole fraction of oxygen should be determined.

Concept Introduction:

Mole fraction: Quantity which defines the number of moles of a substance in a mixture divided by the total number of moles of all substances present.

${\text{x}}_{\text{a}}\text{=}\frac{{\text{n}}_{\text{a}}}{{\text{n}}_{\text{total}}}$

Partial pressure of a gas in the mixture of gases is the product of mole fraction of the gas and the total pressure.

  ${\text{p}}_{\text{a}}\text{=}{\text{x}}_{\text{a}}\text{×}{\text{P}}_{\text{total}}$
