Gases are typically a mixture of several different gases, and each of these gases exerts its own pressure on the walls of the container. The pressure for each of the individual gases is referred to as the partial pressure, or the pressure that the individual gas would exert on the container if it was the only gas in the container.
Dalton’s law of partial pressures states that the total pressure of a mixture of gases is equal to the sum of the partial pressures of each of the individual gases.
What is the total pressure within a gas cylinder if the cylinder consists of 4.54 atm of oxygen, 1.2 atm of nitrogen, and 2.61 atm of argon?
According to Dalton’s law of partial pressures, it states that the
Total pressure of a mixture of gases is equal to the sum of the partial pressures of each of the individual gases.
Given
The cylinder consists of
4.54 atm of oxygen,
1.2 atm of nitrogen,
and 2.61 atm of argon
these are the partial pressures of each individual gases.
hence
Total pressure within gas cylinder is equal to the sum of the partial pressures of each of the individual gases
Total pressure = 4.54 atm of oxygen + 1.2 atm of nitrogen + 2.61 atm of argon = 8.35 atm

Name Dalton's Law of Partial Pressures - Many gas samples are a mixture of gases. For example, air is a mixture of gases. The gases dissolved in blood make up a mixture as well. In a gas mixture, each gas exerts its partial pressure (the specific pressure contribution of the gas to the total pressure of the gas mixture). Dalton's law states that the total pressure of a gas mixture (Pita) is the sum of the partial pressures of the...
