Question

A chemist starts with 1.75 g of dactylic acid and excess methanol and calculates the maximum possible yield to be 1.93 g After the reaction run the chemist finds that the amount of methyl salicylate produced and isolated is only 1.42 g What is percentage yield of the process ?

Answer 1

Answer:

The percentage yield of the reaction = 73.6 %

Explanation:

Step 1: Data given

Mass of salicylic acid = 1.75 grams

the maximum possible yield = 1.93 g

The actual yield = 1.42 grams

Step 2: The balanced equation

C7H6O3 + CH3OH → C8H8O3 + H2O

Step 3: Calculate the percentage yield

Percentage yield = (actual yield / theoretical yield) * 100 %

Percentage yield = (1.42 grams / 1.93 grams ) * 100 %

Percentage yield = 73.6 %

The percentage yield of the reaction = 73.6 %
