1) Watch video: "Determining the Mole Ratio"--5 min. You do not necessarily have to watch the entire video if you understand what is going on after the first equation is demonstrated. The second equation is repetition.

2) Watch video: "Mole Ratio Problems"--21 min. Take careful notes on this one--it is very good.
