Chapter 11, Problem 11.76QP

Interpretation Introduction

Interpretation:

The given mole fraction of Oxygen gas has to be calculated.

Concept Introduction:

The equation is used to determine the mole fraction of ${\text{O}}_{\text{2}}$

${\text{χ}}_{\text{i}}\text{×}{\text{P}}_{\text{total}}\text{=}{\text{P}}_{\text{i}}$

Rearranging the above Equation to solve for mole fraction gives

${\text{χ}}_{\text{i}}\text{=}\frac{{\text{P}}_{\text{i}}}{{\text{P}}_{\text{total}}}$

${\text{χ}}_{\text{i}}\text{=}\frac{\text{2}\text{.8}\text{atm}}{\text{4}\text{.6}\text{atm}}\text{=}\text{0}\text{.61}$
