Find the moles of aspirin (theoretical), theoretical yield (g), and final percent yield.

mass of salicylic acid = 402.5 mg

moles of salicylic acid = 0.002914 moles

volume of acetic anhydride = 1.00 mL

moles of acetic anhydride = 0.01058 moles

moles of aspirin (theoretical) = ?

theoretical yield (g) = ?

mass of crude product = 350.1 mg

mass of recrystallized product = 233.7 mg

final percent yield = ?
