The limiting reagent is the reactant which runs out first. After it runs out, the reactant cannot proceed further. It "limits" the reaction. All other reactants are in "excess". When calculating how much product can be made, always start calculations with the limiting reagent because it determines how much product can be made.

This reagent is the LR. To determine the amounts of product (either grams or moles), you must start with the limiting reagent. Use the amount that you have, not the amount you need. To determine the grams of excess reagent, subtract the amount you need from the amount that you have, then using the molar mass, convert the moles left to grams.
The substance that has the smallest answer is the limiting reagent. 2) Let's say that again: to find the limiting reagent, take the moles of each substance and divide it by its coefficient in the balanced equation. The substance that has the smallest answer is the limiting reagent. You're going to need that technique, so remember it.

Limiting Reagents Learning Objectives . Identify a limiting reagent from a set of reactants. Identifying the limiting reagent, then, is straightforward. However, there are usually two associated questions: (1) what mass of product (or products) is then actually formed? and (2) what mass of what reactant is left over? The first question is straightforward to answer: simply perform a
an excess of one of the reactants. This essentially makes the other the limiting reagents. Getting back to economics, it makes sense to choose the less expensive reagent as one to use in excess.
