Ana Berry · Answer 1

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 %
