To determine the number of s’mores you can make, identify the ingredient that will run out first, known as the limiting reactant, based on the recipe's required quantities. Using an example, if 10 marshmallows, 20 graham crackers, and 10 pieces of chocolate are available, you could make 10 s’mores since the marshmallows or chocolate would limit production.
To determine how many s’mores can be made with the ingredients provided, we need to look at the amounts of each ingredient and find the limiting reactant—the ingredient that will run out first. In this case, you have not specified the exact quantities of graham crackers, marshmallows, and chocolate available, but we can use a given example to illustrate the process.
If you have 10 marshmallows, 20 graham crackers, and 10 pieces of chocolate, the marshmallows and chocolate would be the limiting reactants, as they will both run out after making 10 s’mores. This is because for each s’more, you need one marshmallow and one piece of chocolate. The graham crackers, needed in a 2:1 ratio compared to the marshmallows or chocolate, will not limit the production since you have enough to make 10 s’mores (20 graham crackers).
In stoichiometry, similar to the example given for sandwiches and pancakes above, quantities in recipes need to be proportional. If you run out of one key ingredient, that limits the number of final products you can create, just as the number of cheese slices limited the number of sandwiches you could make.
