Limiting Reagents

A limiting reagent is the chemical in a compound that will be used up first, there by "limiting" the chemical reaction. There are 2 methods that can be used to determine a limiting reagent as pictured below...

Method 1:

Method 2:

Personally, I like to use the method in which I have modified into simpler steps which are:

1. Convert each reactant to moles

2. Multiply by molar ratio

3. Concert back into grams

4. The smaller number is the limiting reagent

Here are some links that should help:
