The chamber is filled uniformly. This would be the case even if the chamber were not evacuated........

Explanation:

#"Dalton's Law of Partial Pressures"# holds that in a gaseous mixture, the partial pressure exerted by a component gas is the same as the pressure it would exert if it alone occupied the container. This is the experimental result: the gas expands to fill the entire chamber.
