Aspirin (c9h8o4) may be synthesized by mixing salicylic acid (c7h6o3) with excess acetic anhydride (c4h6o3).
the balanced equation is c7h6o3 + c4h6o3 c9h8o4 + c2h4o2 when 2.0 g of salicylic acid is mixed with excess acetic anhydride, 1.7 g of aspirin is collected.

what is the percent yield for this reaction?

65.18% is the percent yield for this reaction.

Explanation:

Moles of salicyclic acid =

According to reaction 1 mole of salicyclic acid gives 1 mole of aspirin .

Then 0.01449 mole of salicylic acid will give :

of asprin

Mass of 0.01449 moles of aspirin :

= 0.01449 mol × 180 g/mol = 2.6082 g

Theoretical yield of aspirin = 2.6082 g

Experimental yield of aspirin = 1.7 g

The percent yield for this reaction:

65.18% is the percent yield for this reaction.
