C7H6O3(S) + C4H6O3 → C9H8O4(S) + CH3CO2H


Its not applicable



18.8 g SA x (1 mol SA / 138 g SA) x (1 mol Asp / 1 mol SA) x (180 g Asp / 1 mol Asp) = 24.5 g Asp

 

TY of Asp = 24.5 g

 

%-Yield = (Actual yield / Theoretical yield) x 100%

 

Actual yield = %-Yield x Theoretical yield

 

           = 33.3% x 24.5 g

 

           = 0.333 x 24.5 g

 

          = 8.16 g Aspirin recovered
