  1. SA = salicylic acid
    ASA = aspirin

    mols SA = grams/molar mass = ?
    mols ASA produced = mols SA
    grams ASA = mols ASA x molar mass ASA. This is the theoretical yield (TY)
    Actual yield (AY) either 1.15 or 0.15 depending upon how you read the question.
    % yield = (AY/TY)*100 = ?
