Propane and oxygen react according to the following equation.

C3H8(g) + 5O2>>>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 preessure

1 answer

gas moles and volumes are directly related

you can use dm3 in the given equation
