are all gases less dense than liquid water?
2 answers
I had never thought about that but I suppose it is correct. The largest gas molecule that came to my mind immediately was UF6. Assuming ideal behavior as a gas, it would have a density of about 16 g/L which is considerably less than that of water at 1000 g/L. I tried to find the density of UF6 (gas) on the Internet but I was unsuccessful.
alright thank you for your time/help.
