The apparatus shown here has two gas-filled containers and one empty container, all attached to a hollow horizontal tube. Assume that the containers are of equal volume and ignore the volume of the connecting tube. Which gas has the greater partial pressure after the valves are opened?

Hi everyone here we have a question telling us that the experimental setup depicted in the following diagram shows two gas cylinders of equal volume connected to each other with an empty tube and a stop cock. Which gas will have a greater partial pressure after the stop cock is open and the gasses are allowed to mix. So we are going to assume that the gasses are ideal and that they are mixing uniformly. Since the two containers have equal volumes, the partial pressure of gasses will depend upon the number of gas molecules. The grain has a higher number of molecules, as we can see depicted in the picture, so it will have the higher partial pressure. And that is our final answer. Thank you for watching. Bye.
