**DrBob222**, Thursday, January 31, 2008 at 10:34pmThis may be a limiting reagent problem. You must determine which is the limiting reagent. To do this, I usually simply calculate how much of one reagent is needed if we start with the other. For example,

8.6 L H2 will require how much O2?

8.6 x (1 mol O2/2 mols H2) = 4.3 and we have exactly 4.3; therefore, both are limiting and we have exactly the amount of each we need. Use this same procedure to determine the amount of H2O produced.
