An oxygen cylinder of volume 30 litre has an initial gauge pressure of 15 atm and a temperature of \[27{}^\circ C\]. After some oxygen is withdrawn from the cylinder, the gauge pressure drops to 11 atm and its temperature drop to \[17{}^\circ C\] Estimate the mass (in kg) of oxygen taken out of the cylinder \[R=8.3Jmo{{l}^{-1}}{{K}^{-1}}\], molecule weight of oxygen \[=32.\]
