Which gas shows real behavior?
16 g O2 at STP occupies 11.2 L
1 g Hz in 0.5 L flask exerts pressure of 24.63 atm at 300 K
1 mole NH3 at 300 K and 1 atm occupies volume 22.4 L
5.6 L of CO2 at STP is equal to 11 g
For ideal gas PV = nRT Volume of 1 mole gas at 1 atm pressure and 273 K is 22.4 L and at 300 K and 1 atm pressure volume = 24.63 L.
