Chapter 10, Problem 65E

Interpretation Introduction

Interpretation:

The concentration of ${\text{CO}}_2$ gas in atmosphere is given to be $390\text{ppm}$ . The mole fraction of the ${\text{CO}}_2$ in the atmosphere is to be calculated.

Concept introduction: The mole fraction is calculated by the number of moles of a component in a solution divided by the total number of moles of a solution. It is used to calculate the quantity of the substance in a solution. This concept is based on the Avogadro’s Law. Avogadro’s law states that equal volume of gases contains equal number of molecules at the condition of the same temperature and pressure.

To determine: The mole fraction of the ${\text{CO}}_2$ in the atmosphere.
