At 300 K and under pressure of 100 atm the Z for O2 is 0.96. At 600 K and under pressure of 150 atm the Z for O2 is 0.8 for the same mass of O2. If the volume of O2 at 300 K and 100 atm press is 2L, then what mass of O2 (g) is required to fill a vessel of capacity 200 L at 600 K & 150 atm ?
Text Solution
Verified by ExpertsThe correct answer is:
B
P 2 V 2 = n Z 2 RT 2
150 × 200 = n × 0.8 × 0.082 × 600
or n = 
= 762.2 mole ≡ 24.39 kg
