Effusion Practice Test

Per Graham's law of effusion, how does the molar mass relate to both the rate and time of effusion?

A mixture of neon gas and argon gas is present in a container (container A). There are equal amounts of both gases in the container. A small pinhole is created in the container, allowing the gases to effuse into an empty container (container B). The effusion time is very brief, and the pinhole is eventually plugged, resulting in a mixture of both gases in both containers.

Which of the following statements is true after the pinhole is plugged?
