A gas bulb with volume 3.60 L is filled with 0.227 mol of Ar. It is connected by a valve to another gas bulb of unknown volume, which is filled with 0.144 mol of oxygen. After opening the valve, a total pressure of 1.08 atm is measured. The temperature is held at 20 0C during this process. What is the unknown volume (of the bulb originally filled with oxygen)
