Gas Stoichiometry

Gas StoichiometryVolume RatioFor all gases, the coefficients represent not only a mole ratio, but also a volume ratio

ExampleIn cooking and heating, the combustion of propane is shown by the equation C3H8(g) + 5O2(g) 3CO2(g) + 4H2O(g) How many liters of carbon dioxide is produced from 3.5L of propane?Volume-Mass ExampleFrom the equation CaCO3(s) CaO(s) + CO2(g) How many grams of calcium carbonate is needed to produce 5.0L of carbon dioxide?Mass-Volume ExampleHow many liters of sulfur dioxide will be produced from 18.0g of sulfur? S(s) + O2(g) SO2(g)
