Explain how long should you let the oxygen escape


A 2.00-liter steel cylinder of oxygen gas at 25oC has a pressure of 17.2 atm. suppose you want to reduce the pressure in the cylinder to 15.5 atm, so you allow the oxygen to effuse into a vacuum. Under the identical conditions, this pinhole will allow the 0.017 moles of argon gas to effuse every hour. Explain how long should you let the oxygen escape from the pinhole in order to reduce the pressure from 17.2 atm to 15.5atm?
