Acetone, C₃H₆O, has a vapor pressure of 0.307 bar at 25 ºC. A sample of 0.100 mol acetone is added to a container that contains 1.00 L of argon gas at 1.00 bar pressure and 25 ºC. The volume of the container is then increased to 4.00 L while maintaining the same temperature. What is the pressure in the container after the expansion?
