A 2.00 liter steel cylinder of oxygen gas has a pressure of 17.2 atm at 25 degree celsius. You want to reduce the pressure in the cylinder to 15.5 atm, so you allow oxygen to escape from the cylinder and collect the escaping gas over water. What volume of gas should you collect at 25 degree celsius and 1.00 atm in order to achieve the desired pressure in the cylinder?
