An oxygen cylinder of volume 30 litre has 18.20 moles of oxygen. After some oxygen is withdrawn from the cylinder, its gauge pressure drops to 11 atmospheric pressures at temperature 27∘C27^{\circ} \mathrm{C}27∘C. The mass of the oxygen withdrawn from the cylinder is nearly equal to:

[Given, R=10012 J mol−1 K−1R=\frac{100}{12} \mathrm{~J} \mathrm{~mol}^{-1} \mathrm{~K}^{-1}R=12100​ J mol−1 K−1, and molecular mass of O2=32,1\mathrm{O}_2=32,1O2​=32,1 atm pressure =1.01×105 N/m=1.01 \times 10^5 \mathrm{~N} / \mathrm{m}=1.01×105 N/m]
