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 After some oxygen is withdrawn from the cylinder, its gauge pressure drops to 11 atmospheric pressures at temperature \(27^\circ\ \text{C}\). The mass of oxygen withdrawn from the cylinder is nearly equal to:
[Given, \(\text{R}\,=\, \frac{100}{12}\text{J mol}^{-1}\text{K}^{-1}\) and molecular mass of \(\text{O}_2\,=\, 32\), 1 atm pressure \(=\,1.01 \times 10^5 \text{N/m}\)]
