A sample of methane gas having a volume of 2.80 L at 250C and 1.65 atm was mixed with a sample of oxygen gas having a volume of 35.0 L at 310C and 1.25 atm. The mixture was then ignited to form carbon dioxide and water. Calculate the volume of carbon dioxide formed at a pressure of 2.50 atm and a temperature of 1250C.
