Limiting Reagents

We learned two approaches to solve limiting reagent problems:

Approach 1:
1. Balanced chemical equation
2. Convert all info to moles
3. Calculate the mole ratio from the given info. Compare calculated ration to actual ratio.
4. Use the amount of limiting reagent to calculate the amount of product produced.
5. If necessary, calculate how much is left in excess of non-limiting reagent

Approach 2:
1. Balanced chemical equation
2. Convert info to moles
3. Use stoichiometry for each individual reactant to find mass of product produced
4. The reactant that produces lesser amount is the limiting reagent
5. The reactant that produces larger amount is excess reagent
6. To find amount of remaining excess reactant, subtract the mass of excess reagent consumed from total mass of excess reagent given.
**This approach is the one I prefer to use
