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 After some oxygen is withdrawn from the cylinder, its gauge pressure drops to 11 atmospheric pressure at temperature 27°C. The mass of the oxygen withdrawn from the cylinder is nearly equal to:

[Given,
R=10012R = \frac{100}{12} Jmol−1^{-1} K−1^{-1}, and molecular mass of O2_2 = 32, 1 atm pressure = 1.01×1051.01 \times 10^5 N/m]

Show answer and solution
Sol. Number of moles left
