The concepts of stoichiometry are similar to those in a cooking recipe. For example, suppose we use the following pizza recipe: 1 crust + 5 ounces tomato sauce + 2 cups cheese --> 1 pizza The recipe contains the numerical relationship between the pizza ingredients. It says that if we have 2 cups of cheese -- and enough of everything else -- we can make 1 pizza. We can write this relationship as a ratio between the cheese and the pizza. 2 cups cheese : 1 pizza 1) How many pizzas can we make if we have 6 cups of cheese? Assuming that we have enough of everything else. Show work by using the ratio as a conversion factor to calculate the number of pizzas. 2) Suppose that we have 4 crusts, 15 ounces of tomato sauce, and 10 cups of cheese theoretically. How many pizzas can we make? 3) Which one of three ingredients in the above case can give the least amount of pizzas?

2 cups cheese : 1 pizza
1) How many pizzas can we make if we have 6 cups of cheese? Assuming that we have enough of everything else. Show work by using the ratio as a conversion factor to calculate the number of pizzas.
2) Suppose that we have 4 crusts, 15 ounces of tomato sauce, and 10 cups of cheese theoretically. How many pizzas can we make?
3) Which one of three ingredients in the above case can give the least amount of pizzas?
4) If this were a
5) Suppose we go on to cook our pizzas and we have enough ingredients for the above, we end up with only two pizzas. If this were a chemical reaction, what is the actual yield? And what is our percent yield?
