Stoichoimetry
- Stoichiometry is the process of measuring quantitatively the mass and quantity relationships among reactants and products in a given reaction.
The equation of the reaction shows the stoichiometry between reactants and products.
For the given reaction, the equation of reaction is as follows:
1M + 2Gc + 3Cp ----> 1Gc2MCp3
where:
- Gc = Graham Cracker
- M = Marshmallow
- Cp = Chocolate pieces
- S’more = Gc2MCp3
From the equation of reaction:
- 1 marshmallow, 2 Graham cracker and 3 chocolate pieces are required to make 1 S'more
Calculating the number of S'mores and the limiting reactant of the given reaction
The stoichiometric equation is: 2Gc + 1M + 3Cp ----> 1Gc2MCp3
The ratio of Gc to M to Cp is 2 : 1 : 3
Reaction 1. 4 Gc + 2M + 5 Cp
The ratio of Gc to M to Cp in the reaction above is 2 : 1 : 2.5
- Therefore the limiting reagent is Cp
3 Cp makes 1 S'more
5 Cp will make 5 * 1/3 S'more = 1.6 S'mores
- Therefore, 1.6 S'mores are produced.
Reaction 2. 6 Gc + 2M + 9 Cp
The ratio of Gc to M to Cp in the reaction above is 3 : 1 : 4.5
- Therefore the limiting reagent is M
1 M makes 1 S'more
2 Cp will make 2 * 1/1 S'more = 2 S'mores
- Therefore, 2 S'mores are produced.
Reaction 3. 5 Gc + 3M + 9 Cp
The ratio of Gc to M to Cp in the reaction above is 1.6 : 1 : 3
- Therefore the limiting reagent is Gc
2 Gc makes 1 S'more
5 Gc will make 5 * 1/2 S'more = 2.5 S'mores
- Therefore, 2.5 S'mores are produced.
Reaction 4. 7 Gc + 1M + 6 Cp
The ratio of Gc to M to Cp in the reaction above is 7 : 1 : 6
Therefore the limiting reagent is M
1 M makes 1 S'more
- Therefore, 1 S'more is produced.
The limiting reagent and the number of S'mores produced for each of the reactions is given below:
1. The limiting reagent is Cp; 1.6 S'mores are produced.
2. The limiting reagent is M; 2 S'mores are produced.
3. The limiting reagent is Gc; 2.5 S'mores are produced.
4. The limiting reagent is M; 1 S'more is produced.
