True/False - Gas Characteristic Question?

Gases are different from solids and liquids because gases have average densities on the order of 10-3 g/mL.





I'm guessing that this is true because gases tend to have lower densities than solids and liquids. What do you think?True/False - Gas Characteristic Question?
air has a density of about 1.29 grams / litre





that's 1.29 X 10^-3 grams / ml





=================================





gases become a touch more dense at STP





that STP., the density is found by


dividing the molar mass of the gas by the STP molar volume 22,400 ml,





carbon monoxide: 28 g/22,400 ml = 1.25 e-3 g/ml





oxygen 32g/22400ml = 1.4 e-3 g/ml








yes there will be exceptions,


but it is true enough
