1.15g of acetylsalicylic ia recovered from an aspirim synthesis reaction that began with 2g of salicylic acid, what would be the percentage yield for the preparation? show your computations

(1.15g/2g)x100=????
Salicylic Acid + Acetic Anhydride.......=>..........Aspirin + Acetic Acid
…..C₇H₆O₃…….. + …..C₄H₆O₃……… =>……...C₉H₈O₄ + HC₂H₃O₂
2g/(138g/mol)….+.....(excess)………=> ?g(Theoretical) + ----------
=0.015mole C₇H₆O₃..…………………=>…0.015mole(180g/mole) = 2.61g Aspirin (Theoretical Yield)
%Yield = (Actual Yield/Theoretical Yield)100% = (1.15g/2.61g)100% = 44.1% Yield
…..C₇H₆O₃…….. + …..C₄H₆O₃……… =>……...C₉H₈O₄ + HC₂H₃O₂
2g/(138g/mol)….+.....(excess)………=> ?g(Theoretical) + ----------
