stoichiometry! Please guys help me out!
hi all..

I tried to answer this question... but some how I cant... would some please answer it and explane to me what steps he/she used and how! :confused:
thanks a lot the question is :
how many cookies could you make from 1000 cups of flour, 40 sticks of margarine, 500 cups of brown sugar, 10 dozen eggs, 1.00L of salt, 1.00 L of vanilla, 1.00 L baking soda, and 100 oz. chocolate chips? (4.9 mL=1 tsp.)

if how ever :
materials: 2 and 1/4 cups all-purpose flour, 1 teaspoon baking soda, 1 teaspoon salt, 1 cup butter or margiarine, softened, 3/4 cup granulated sugar, 2 teaspoon vanilla extract, 2 eggs, 3 ounces chocolate chips, ***should yield 48 cookies***

please guys help me out...
thanks again..

ooo. That's a lot of numbers! I don't remember all of the steps. But I know you'll need to start with some conversions. You need to convert the 1.00L of vanilla and 2 tsp of vanilla so that they're the same what's it called, sorry, totally blanking on the right word. But like, 2 tsp of vanilla needs to be changes to x # of L. same with salt. And don't forget 10 dozen eggs means 120 eggs. ( I always forget details like that and will throw in 10 eggs to 2 eggs ;) )

Thanks... but still I don't get it..
But thanks for that info

Well to start with, think about how many cookies you could get if you had only 1000 cups of flour and an infinite amount of every other supply. That would mean you could make 1000/2.25 batches of cookies, so 444.44 batches. Each batch is 48 cookies so 444.44 * 48 = 21333.33 total cookies.

Now remember that we can only get this many cookies if we have an infinite number of all the other ingredients. Now how many cookies could you get with 40 sticks of margarine assuming you had an infinite amount of every other ingredient. Do this for every ingredient to find out how many cookies can be made with that ingredient assuming an infinite amount of all the other ingredients.

The ingredient that produces the least amount of cookies is what you'll actually be able to make before running out of one of the ingredients meaning you won't be able to make any more cookies.
