    A compressed cylinder of gas contains \[1.50\times {{10}^{3}}g\] of \[{{N}_{2}}\] gas at a pressure of \[2.0\times {{10}^{7}}\] Pa and a temperature of \[17.1{}^\circ C\]. What volume of gas has been released into the atmosphere if the final pressure in the cylinder is \[1.80\times {{10}^{5}}\] Pa? Assume ideal behaviour and that the gas temperature is unchanged.

    A) 1264 L             

    B) 126 L

    C) 12600 L           

    D) 45 L

    Correct Answer: A

    Solution :

    [a] \[^{n}{{N}_{2}}=53.57\,mole\] \[\frac{{{P}_{1}}}{{{P}_{2}}}=\frac{{{n}_{1}}}{{{n}_{2}}}\] \[{{n}_{2}}=\frac{1.8}{200}=0.009\times 53.57=0.48213\] \[^{n}{{N}_{2}}\] escape =53.087 Volume \[=\frac{nRT}{P}=1264\,L\]
