Chapter 10, Problem 91RQ

Interpretation Introduction

Interpretation:

The volume of wet methane gas that is required in order to collect the given amount of dry methane gas in the sample is to be calculated.

Concept Introduction:

Dalton’s law states that each gas exerts its own pressure, called the partial pressure of that gas, and if there is mixture of different gases in a container, then the total pressure of the mixture of gases is estimated by the addition of the partial pressure values of each of the gases present in that respective mixture.

Mathematically it is expressed as:

$P_{\text{total}}=P_{\left(1\right)}+P_{\left(2\right)}$

The combined gas law equation is expressed as:

$\frac{P_1{V}_1}{T_1}=\frac{P_2{V}_2}{T_2}$

Here, $P_1$ is the given pressure, $V_1$ is the given volume, $T_1$ is the given temperature, $P_2$ is the pressure value used for determining the volume of carbon monoxide, $V_2$ is the volume of carbon monoxide, and $T_2$ is the temperature during the collection of the gas.
