A chemist is commissioned to produce twenty pallets of aspirin: C7H6O3 (salicylic acid) + C4H6O3 (acetic anhydride) → C9H8O4 (aspirin) +C2H4O2 (acetic acid)

Given a bottle contains 500 tablets (each containing 325 mg of aspirin). A case contains 144 bottles. A pallet contains 150 cases.

A 55 gallon drum of acetic anhydride
(density = 1.08 g/mL) costs the chemist $2640.00

A 50 pound bag of salicylic acid costs the chemist $508.00

How many kilograms of salicylic acid are required if the aspirin is produced with a 78.2% yield?

How many liters of acetic anhydride are required?

What is the total cost of the reactants used?
