Chapter 5, Problem 5.130P

Interpretation Introduction

Interpretation:

The grams of ${\text{CO}}_2$ were originally present in the mixture of ${\text{CO}}_2$ and $\text{Kr}$ is to be calculated. And also the grams of $\text{Kr}$ recovery is to be calculated.

Concept introduction:

The expression to calculate the partial pressure of the gas is as follows:

$P_{\text{gas}}=X_{\text{gas}}\cdot P_{\text{total}}$

Here, $P_{\text{gas}}$ is the partial pressure of the gas, $X_{\text{gas}}$ mole fraction of the gas and $P_{\text{total}}$ is the total pressure.

The expression to calculate the mole fraction of the gas is as follows,

$X_{\text{gas}}=\frac{\text{Moles of gas}}{\text{Total moles}}$

Here, $X_{\text{gas}}$ is the mole fraction of the gas.
