    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 %
