Propane gas, C3H8, reacts with oxygen to produce water and carbon dioxide. Propane has a density of 2.02 g/L at room temperature. C3H8(g)+5O(g)-->3CO2(g)+4H2O(l). a) How many moles of water form when 5.00L of propane gas completely reacts? b) How many grams of CO2 are produced from 18.5 g of oxygen gas and excess propane? c) How many grams of H2O can be produced from the reaction of 8.50*10^22 molecules of propane gas
