Chapter 6, Problem 6.182AP

Interpretation Introduction

Interpretation: The mole fraction of water vapor in the gas sample collected over water in problem $6.181$ with the help of Dalton’s law of partial pressure is to be calculated.

Concept introduction: The Dalton’s law of partial pressures state that, “the total pressure exerted by a mixture of gases is equal to the sum of the partial pressures of the gases in the mixtures”.

The mole fraction of the water vapor in the gas with respect to partial pressure is calculated by the formula,

$P_{\text{Water}}=X_{\text{Water}}\times P_{\text{Total}}$

To determine: The mole fraction of water vapor in the gas sample with the help of Dalton’s law of partial pressure.
