Chapter 20, Problem 20.6QP

Interpretation Introduction

Interpretation:

The partial pressure of carbon dioxide has to be calculated when the atmospheric pressure is $\text{754 mmHg}$.

Concept Introduction:

Partial pressure:

The product of total pressure of gases and number of mole of individual gas is the partial pressure of a gas.

$\begin{array}{l}{\text{P}}_{\text{i}}{\text{=P}}_{\text{total}}{\text{X}}_{\text{i}}\\ \\ {\text{X}}_{\text{i}}\text{is}\text{mole}\text{fraction}\end{array}$

${\text{P}}_{\text{i}}$ is individual pressure of a gas

${\text{P}}_{\text{Total}}$ is total pressure of all gases.

Mole fraction:

Mole fraction is the ratio number of moles of a species to that of total number of moles of solution.

$\text{X}\text{=}\frac{\text{Moles}\text{of}\text{a}\text{species}}{\text{Total}\text{moles}\text{of}\text{solution}}$
