This is hands down the easiest, fastest, most reliable way to solve stoichiometry problems. I am not kidding. THE BEST. I call it the chart method. This PowerPoint has gram to mole conversions and % composition also. The instructions for stoichiometry are clear and procedural. If you are looking for your students to save time on timed tests, this is the method for you. My chemistry students ask for this when they get to college since the traditional method is crazy lots of work. An example for limiting reactants is included even though my standards do not cover it. The PowerPoint is animated so that you can go the speed you prefer.
