What is the theoretical yield of waffles if you have 6 cups of flour, 9 eggs and 2 tbs of oil?
Given: 2 cups flour + 3 eggs + 1 tbs oil 4 waffles

8 waffles

Explanation:

First, find the limiting reagent.  Divide the amount you have by the amount that is needed.  The smallest number is the limiting reagent.  For this problem, the limiting reagent is oil.

6 cups of flour/2 cups of flour = 3

9 eggs/3 eggs = 3             2 tbsp of oil/1 tbsp of oil = 2

This means that we can double the recipe since we have enough of each ingredient to make two batches.  Multiply the entire equation by 2.  This should give you   4 cups of flour  +  6 eggs  +  2 tbsp of oil  ==>  8 waffles.

You should theoretically get 8 waffles.
