A sample of butane gas, C4H10 of unknown mass is contained in a vessel of unknown volume V at 25 ∘C and a pressure of 760 mm Hg. To this vessel, 8.6787 g of neon gas is added in such a way that no butane is lost from the vessel. The final pressure in the vessel is 1920 mm Hg at the same temprature. Calculate the volume of the vessel and the mass of butane.

1.	A sample of butane gas, C4H10 of unknown mass is contained in a vessel of unknown volume V at 25 ∘C and a pressure of 760 mm Hg. To this vessel, 8.6787 g of neon gas is added in such a way that no butane is lost from the vessel. The final pressure in the vessel is 1920 mm Hg at the same temprature. Calculate the volume of the vessel and the mass of butane.
Answer» A sample of butane gas, $C_{4} H_{10}$ of unknown mass is contained in a vessel of unknown volume $V$ at $25^{\circ} C$ and a pressure of $760 mm Hg$ . To this vessel, $8.6787 g$ of neon gas is added in such a way that no butane is lost from the vessel. The final pressure in the vessel is $1920 mm Hg$ at the same temprature. Calculate the volume of the vessel and the mass of butane.
