Question- A sample of propane gas (C3H3) having a volume of 1.80L at 25 deg C and 1.65atm was mixed with a sample of oxygen having a volume of 35.0L at 31 deg C and 1.25atm. The mixture was ignited to form carbon dioxide and water. Write the balanced equation. What is the limiting reagent? What is the maximum number of grams of water which can form from this reaction? Find the number of moles of excess reactant at STP.
