Intro to Cookie LabStoichiometry is all about writing recipes.Let’s apply stoichiometry to a chocolate chip cookie recipe:a. Flour - C4H8O4

b. Baking Soda - NaHCO3

c. Salt - NaCld. Butter - C9H14O6

e. Sugar (brown and white) - C12H22O11

f. Vanilla extract - C8H8O3

g. Egg - C6H12O3N2

h. Chocolate chips - C4H8O3
