An ideal gas was contained in a glass vessel of unknown volume with a pressure of 0.960 atm. Some of the gas was withdrawn from the vessel and used to fill a 25.0-mL glass bulb to a pressure of 1.00 atm. The pressure of the gas remaining in the vessel of unknown volume was 0.882 atm. All the measurements were done at the same temperature. What is the volume of the vessel?
