Furthermore, you provide the final mass of the acetophenone you made assuming that is dried to constant mass after satisfactory purification. The problem is you do not list the amount of starting material. It is not sufficient to just include the molar equivalents of reagent unless the grams and therefore moles of 1-phenylethanol is included. There is not enough information to answer the question. The other problem is that all limiting reagent questions require a balanced chemical equation. Please start there first.
