Can you help me find the oxygen remaining?
Propane and oxygen react according to the following equation. C3H8(g) + 5O2(g) → 3CO2(g) + 4H2O(g)
Calculate the volume of carbon dioxide and water vapour produced and the volume of oxygen remaining, when 20.0 dm3 of propane reacts with 120.0 dm3 of oxygen.
All gas volumes are measured at the same temperature and pressure.
