Editing Limiting reagent (section)

===Shortcut===
It can be seen from the example above that the amount of product (Fe) formed from each reagent X (Fe<sub>2</sub>O<sub>3</sub> or Al) is proportional to the quantity

<math>\frac{\mbox{Moles of Reagent X }}{\mbox{Stoichiometric Coefficient of Reagent X}}</math>

This suggests a shortcut which works for any number of reagents. Just calculate this formula for each reagent, and the reagent that has the lowest value of this formula is the limiting reagent. We can apply this shortcut in the above example.
