Question

Quizplus · Accepted Answer

Container C has the largest partial pressure of helium because it has the highest number of white circles in proportion to the number of dark circles. The partial pressure of a gas is directly proportional to the number of atoms or molecules of that gas present in the container, so the container with the most helium atoms will have the highest partial pressure of helium.
