A gas cylinder contains 320 g oxygen gas at 24.6 atm pressure and 27ºC. What mass of oxygen would escape if first the cylinder were heated to 133ºC and then the valve were held open until the gas pressure was 1.00 atm, the temperature being maintained at 133ºC ? (R = 0.0821 L. atm/K/mole)
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
(310.4 g escaped)
= 
∴ 
= 
∴ n 2 = 0.3
∴ Mass of oxygen left = 0.3 × 32 = 9 g
∴ Mass of oxygen escaped = 320 – 9.6 = 310.4 g.
