A quantity of N2 gas originally held at 3.80 atm pressure in a 1.00 L container at 26.0ºC is transferred to a 10.0 L container at 20.0ºC. A quantity of O2 gas originally at 4.75 atm and 26.0ºC in a 5.00 L container is added to the 10.0 L container already containing the N2. a) Draw a diagram outlining this experiment, labeling the various quantities. b) Calculate the total pressure in the new container. c) What is the mole fraction...
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...

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...
Topic: Practice exercise on gas laws. You must write the equation you are using to solve the exercise. 1. A sample of Argon gas occupies an initial volume of 5.40 L when its pressure is 6.52 atm. What will be the final pressure of the gas if its volume increases to 9.73 L? 2. An unknown gas occupies an initial volume of 0.256 L when its temperature equals 121ºC. What will be the final volume if the temperature drops to...
