Aspirin (C9H8O4) may be synthesized by mixing salicylic acid (C7H6O3) with excess acetic anhydride (C4H6O3).
diamong [38]

Answer:

65.18% is the percent yield for this reaction.

Explanation:

C_7H_6O_3 + C_4H_6O_3\rightarrow C_9H_8O_4 + C_2H_4O_2

Moles of salicyclic acid = \frac{2.0 g}{138 g/mol}=0.01449 mol

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

Then 0.01449 mole of salicylic acid will give :

\frac{1}{1}\times 0.01449 mol=0.01449 mol 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:

\%(Yield)=\frac{\text{Experimental yield}}{\text{Theoretical yield}}\times 100

=\frac{1.7 g}{2.6082 g}\times 100=65.18\%

65.18% is the percent yield for this reaction.

Why is a measured amount of water needed to determine the specific heat of a metal object?
shutvik [7]
This  is  because  absorbed  heat  energy or  released  by  water  is dependent on  mass of  water.
q=mc delta  T
where  q is  the amount  of  energy  required,   m  is  the  mass , C  is   the  specific  heat  capacity  and  delta  T is change  in  temperature.
