Chapter 5.5, Problem 5.7QC

Interpretation Introduction

Interpretation:

A vessel contains nitrogen (${\text{N}}_{\text{2}}$) and water vapor (${\text{H}}_{\text{2}}\text{O}$) under $2.0\text{15 atm}$ pressure. The partial pressure of the water vapor, when the partial pressure of nitrogen gas is $1.90\text{8 atm}$ should be calculated.

Concept Introduction:

The partial pressure of water vapor can be calculated using Dalton’s law of partial pressures.

According to Dalton’s law, the total pressure of the mixture of gases is equal to the sum of partial pressures of the individual gas.

$P_T=P_1+P_2+\mathrm{.....}+P_n$.

Where,

$P_{\text{T}}=$ Total Pressure of the mixture.

$P_1$, $P_2$ and $P_n$ are pressure of each individual gas present in the mixture.
