## Answers ( )

Explanation:

What is the “theoretical yield” of cookies from each of the “reactants?”

Theor. yield from eggs

=

12

eggs

×

1

egg

=

Theor. yield from vanilla

=

24

tsp vanilla

×

1

tsp vanilla

=

Theor. yield from salt

=

82

tsp salt

×

0.5

tsp salt

=

Theor. yield from baking soda

=

84

tsp baking soda

×

0.5

tsp baking soda

=

Theor. yield from chocolate chips

=

3

cups chocolate chips

×

1.333

cups chocolate chips

=

Theor. yield from sugar

=

11

cups sugar

×

0.5

cup sugar

=

Theor. yield from brown sugar

=

4

cups brown sugar

×

0.5

cup brown sugar

=

Finally, “we leave it as an exercise for the student” to calculate that

Theor. yield from margarine = 72 cookies

b. Identify the limiting reactant

The limiting reactant is the amount of chocolate chips because they can produce the smallest amount of cookies.

c. Determine the theoretical yield

The theoretical yield is 54 cookies, because that is all you can get from the chocolate chips provided.
