In summary, you have learned a method to
determine how much of every component in a chemical equation can be produced or is needed
when given 1 (or possibly 2) reactants. The basics that you should remember are:
 | Equations are viewed as standard recipes, something a student can
relate to. |
| Unlike ordinary recipes, each of the
ingredients has to be converted to units called moles. |
| A multiplier can be found using the algorithm:
M~
= moles given / Moles from recipe or
the coefficient |
| The standard recipe can be scaled up or shrunken down
by applying the multiplier to all components of the equation thereby
creating an effective equation. |
| Every problem has a mole to mole component, and the more difficult
ones have extensions that start and/or end in matter in different
units |
| Limiting reactant problems can be solved like all of the other
problems, the only difference would be to calculate multipliers for each of the
reactants. The reactant with the smallest multiplier is limiting.
A final message: The method presented here is not the traditional method found in
textbooks every where. I believe it is a better way to do stoichiometry and so far,
the experts who have seen it tend to agree. Please feel free to send comments and
suggestions.
