Hydrogen, chlorine, oxygen, phosphorus and sulfur in their gaseous state have a molar mass half of what they should be (roughly equal to their atomic mass), causing these gases to be much lighter than normal. Carbon dioxide, steam and natural gas have correct molar masses, but due to the lower molar mass of the other gases this makes them comparatively heavier than they should be (carbon dioxide is 175% heavier than oxygen when it should be 37.5% heavier, and 59% heavier than chlorine when it should be 37% lighter).
Steps to Reproduce
Constant issue. Becomes apparent whenever the gases in question interact.
