Q. 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$°$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) 1260 L
(b) 126 L
(c) 12600 L
(d) 45 L
