Sep 18, 2014 · This is the densest gas that strictly meets all the criteria in the OP. If we relax the criteria a bit: Perfluorohexane is just over the boiling point limit at $56\ \mathrm{^\circ C}$ , but it has a molar mass of $338\ \mathrm{g/mol}$ which makes it slightly denser in gas form than tungsten hexafluoride ( $\ce{WF6}$ ).

Feb 11, 2016 · It is hence theoretically possible to achieve a gas with a greater density compared to that one of a liquid, and also the coexistence of the two phases should be possible in certain conditions but the pressure required won't allow you to observe it. Bubbles sinking down? That won't happen also if there was a denser gas compared to a liquid.

Gas molecules in the air continuously collide with each, shoot off in different directions etc. This constant motion is like stirring a fluid. You wouldn't observe perfect density separation in a container with oil and water in it if you keep shaking/stirring it.
