Question

Your favorite recipe for preparing 100 brownies requires the following: 6 eggs, 5 cups flour, and 2 sticks of butter. How many eggs would be required to yield 50 brownies?

Question options:

1 egg


2 eggs


3 eggs


4 eggs

Answer 1

The answer is c because the ratio of 100 to 50 is 2:1, and so since there is 6 eggs required to make 100 brownies, you divide 6 by two and you get 3.

Answer 2

Correct answer: C) 3 eggs

The given recipe for preparing 100 brownies,

6 eggs + 5 cups flour + 2 sticks butter ----> 100 brownies

Assuming the number of each starting material/ product as the moles of each reactant/product. The mole ratios of the different reactants and product is:

`(6 eggs)/(100 brownies)`;
`(5 cups fluor)/(100 brownies)`;
`(2 sticks butter)/(100 brownies)`

We would need the mole ratio of eggs/brownies in order to find out the number of eggs required to prepare 50 brownies.

`50 brownies * (6 eggs)/(100 brownies) = 3 eggs`
