Explanation / Answer

General reaction of formation of aspirin :

Salicyclic acid + acetyl chloride or acetic anhydride - - - - > aspirin,

And salicyclic acid is the limiting reagent here,

Now,

Since percent yield = ( actual yield / theoratical yield) * 100

Actual yield =0.6986 g (given)

Theoretical yield = moles of limiting reagent *( stoichiometric coefficient of product / stoichiometric coefficient of reaction) * molar mass of the product (aspirin)

Theoretical yield = 7.82 * 10^-3 mol * (1/1) * 180.157 gmol-1

Theoretical yield = 1.40 g

Put the values in above formula of percent yield , we getp

Percent yield = ( 0.6986 / 1.40) *100

Percent yield = 49.9 %
