Nitrogen (density=0.00125 g/cm3), oxygen (0.001429 g/cm3), carbon dioxide (0.001977 g/cm3), and argon (0.001784 g/cm3) are all gases in the Earth's atmosphere. Mad Scientist Trotzky is doing an experiment where all those gases are in flask. This is how they will layer according to their densities from the top of the flask to the bottom
What is nitrogen, oxygen, argon, then carbon dioxide?
