Gas Stoichiometry

Q. Nitrogen monoxide is a pollutant commonly found in smokestack emissions. One way to remove it is to react it with ammonia. 4 NH3(g) + 6 NO(g) -> 5N2(g) + 6H2O(l) How many liters of ammonia are required to change 24.6 L of nitrogen monoxide to nitrogen gas? Assume 100% yield and that all gases are measured at the same temperature and pressure.

Gas Stoichiometry

Q. A sample of methane gas, which had a volume of 2.80 m3 and a pressure of 1.65 Pa at 25.0 oC, was mixed with a sample of oxygen gas which had a volume of 35.0 m3 and a pressure of 1.25 Pa at 31.0 oC in a closed container. This gas mixture is ignited (i.e. a combustion reaction) and produces carbon dioxide and water according to the reaction equation below. What volume of CO2 will be produced at a pressure of 2.50 Pa and a temperature of 125 oC? (Assume that the gases all behave ideally).
