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.

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
