You are making cookies and are missing a key ingredient eggs. You have plenty of the other ingredients, except that you have only 1.33 cups of butter and no eggs. You note that the recipe calls for 2 cups of butter and 3 eggs (plus the other ingredients) to make 6 dozen cookies. You telephone a friend and have him bring you some eggs. a. How many eggs do you need? b. If you use all the butter (and get enough eggs), how many cookies can you make? Unfortunately, your friend hangs up before you tell him how many eggs you need. When he arrives, he has a surprise for youto save time he has broken the eggs in a bowl for you. You ask him how many he brought, and he replies, All of them, but I spilled some on the way over. You weigh the eggs and find that they weigh 62.1 g. Assuming that an average egg weighs 34.21 g: c. How much butter is needed to react with all the eggs? d. How many cookies can you make? e. Which will you have left over, eggs or butter? f. How much is left over? g. Relate this question to the concepts of chemical stoichiometry.
