How to find the mass of the salicyclic acid with 155 kg of Asprin

Question

C7H6O3 + C4H6O3 -> C9H8O4 + C2H4O2

(salicylic)  (acetic an) (aspirin)  (acetic acid)

Find mass of salicyclic acid needed to produce 155 kg of asprin.



Answer 1

Assuming that acetic anhydride is not the limiting reagent, first balance the equation, the convert the mass of aspirin to moles of aspirin using the molar mass, then use the mole to mole ratio to find the moles of salicylic acid needed, finally convert those moles to grams using the molar mass.
