    Answer:

    Explanation:

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

    Theor. yield from eggs

    =

    12

    eggs

    ×

    24 cookies

    1

    egg

    =

    288 cookies

    Theor. yield from vanilla

    =

    24

    tsp vanilla

    ×

    24 cookies

    1

    tsp vanilla

    =

    576 cookies

    Theor. yield from salt

    =

    82

    tsp salt

    ×

    24 cookies

    0.5

    tsp salt

    =

    3936 cookies

    Theor. yield from baking soda

    =

    84

    tsp baking soda

    ×

    24 cookies

    0.5

    tsp baking soda

    =

    4032 cookies

    Theor. yield from chocolate chips

    =

    3

    cups chocolate chips

    ×

    24 cookies

    1.333

    cups chocolate chips

    =

    54 cookies

    Theor. yield from sugar

    =

    11

    cups sugar

    ×

    24 cookies

    0.5

    cup sugar

    =

    528 cookies

    Theor. yield from brown sugar

    =

    4

    cups brown sugar

    ×

    24 cookies

    0.5

    cup brown sugar

    =

    192 cookies

    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.
