can u tell me whats the most imprtant subject i need to know for molecular composition of gases ? and for physical characteristics of gases?
I suppose chemistry but you probably already know that?
i mena the imprtant things that i need to know for these chapters
formula of the gases, atoms to the molecule
omg thxs :DDDDD
You need not memorize all of the densities. You can calculate them at STP by molar mass/22.4 = density in g/L.
