Question

Which gas is the most dense at STP?

Answer 1

CO, NO, N2 or O2?

I would think it's O2, since it has the most mass of all of them

and 32/22.4 > then the rest..?

however my answer key says it's N2..

Answer 2

i agree with you it should be \(O_2\)

Answer 3

Since were treating them as ideal gases, the same number of molecules are present in a given volume and so it's only dependent on the Molar mass

Answer 4

Yeah, I was thinking maybe there was some weird special exception for nitrogen that I missed, but I guess not

Answer 5

thanks
