Chapter 21, Problem 21.7QP

Interpretation Introduction

Interpretation: The mole fraction and the concentration for given gas under given conditions should be determined.

Concept Introduction:

Partial pressure: The partial pressure for a gas is obtained by the multiplication of total pressure of the gas with the mole fraction of the gas. It is the pressure of individual gas present in the mixture of gases.

$\text{Partial}\text{Pressure}\text{for}\text{gas}\text{=}\text{Mole}\text{fraction}\text{for}\text{that}\text{gas}\text{×}\text{Total}\text{pressure}$

Mole Fraction: The mole fraction is given by dividing concentration of one component in the mixture by the total components present in the mixture.

Moles: It is the number of particles present in the given specific substance. The formula used to identify the moles present in given mass of a compound is as follows,

$\text{x}\text{moles}\text{=}\frac{\text{Given}\text{mass}\text{of}\text{the}\text{sample}}{\text{Molecular}\text{mass}\text{of}\text{the}\text{sample}}$

Molar mass: It is the total mass of the substance including all the number and the mass of the elements present in substance.

To determine: The mole fraction of carbon dioxide and the concentration should be determined.
