If you took a set of doubles with the isolation manifold closed, and filled one tank with 100% O2, and the other with 100% He. Both tanks to the exact same pressure and temperature....
Unless you have an orifice that is only the diameter of 1 atom, when you open the isolation manifold the 2 tanks will eventually become thoroughly mixed. How long will that take? I don't know, you'll need to break out the slide rule. I believe these are the ideal gas laws dealing with diffusion and Effusion. The gas particles are constantly in motion, and all the O2 molecules are trying to get as far away from each other as possible; same with the He molecules.
