In the gas phase, nitrogen dioxide is actually a mixture of nitrogen dioxide
Interpretation:
The partial pressure of
Concept introduction:
According to Dalton’s law, the total pressure of a mixture oftwo or more nonreactive gases is equal to the individual partial pressure of the gases present in the mixture. The pressure exerted by a gas in the mixture of gases is called its partial pressure.
Answer to Problem 122AP
Solution:
Explanation of Solution
Given information: The density of mixture is
The pressure of the gas is
The average mass of a gaseous mixture is calculated by the expression as follows:
Here,
Substitute the values of
The sum of molar masses of each component is equal to the average molar mass with respective mole fractions.
The mole fraction of each component is calculated by the expression as follows:
Here,
Substitute the values of
On solving further, we get,
Partial pressure of a gas is the product of its mole fraction and the total pressure of the mixture of gases.
