Question

The gases carbon dioxide, oxygen, and argon are mixed in a container. All gases have the same partial pressure, and the total pressure of the container is 32,680 Pa. What is the partial pressure of argon ?

Answer 1

The partial pressure of argon can be calculated simply by dividing the total pressure by 3. This gives an answer equivalent to 10893.33 Pa. The clue behind this is the statement "all gases have the same partial pressure". This follows Dalton's Law of Partial Pressures which states that the total pressure is equal to the sum of the individual partial pressures.
