more than the theoretical weight

(B) The theoretical weight is calculated based on the assumption that the substance is $100\%$ pure. Since the sample is impure,a portion of the weighed mass consists of impurities that do not participate in the reaction. Therefore,to obtain the required amount of the active compound,one must weigh more than the theoretical weight to compensate for the impurities present in the sample.
