Chapter 10, Problem 142AP

Interpretation Introduction

Interpretation:

The reason for squirted water on adding the small amount of water in medicine dropper is to be explained.

Concept Introduction:

The mole fraction of an individual gas for a combination of gases is the ratio of the moles of the individual gas to the total number of moles.

${\chi }_i=\frac{n_i}{n_{\text{total}}}.$

Here, ${\chi }_i$ is the mole fraction of individual gas, $n_i$ is the mole fraction of individual gas, and $n_{\text{total}}$ is the total number of moles.

Also, the mole fraction of an individual gas for the combination of gases can be calculated from the ratio of the partial pressure of the individual gas to the total pressure of the combination.

${\chi }_i=\frac{P_i}{P_{\text{total}}}.$

Here, ${\chi }_i$ is the mole fraction of individual gas, $P_i$ is the partial pressure of individual gas, and $P_{\text{total}}$ is the total pressure.
