If 26.4 L of H2 reacted with 13.2 L of O2 at STP, what is the volume of the gaseous water collected assuming that none of it condenses?
according to the balancedequation, it it remains at the same temperature...
every two volumes of H2 reacted to one volume of O2 yields 2 volumes of H2O.
so if one volume = 13.2liters, I bet you get 26.4 liters H2O
