Question -The compressibility factor for nitrogen at 330 K and 800 atm is 1.90 and at 570 K and 200 atm is 1.10. A certain mass of N2 occupies a volume of 1 dm3 at 330 K and 800 atm. Calculate the volume occupied by same quantity of N2 gas at 750 K and 200 atm.
Options:
A .  1 L
B .  2 L
C .  3 L
D .  4 L
Answer: Option D : D Z=PVnRT⇒1.90=1×800n×R×330 n=1×8001.90×R×330 Z=1.10=V×200n×R×570 1.10=V×200×1.90×R×330800×R×570 V = 4L
