Guidelines for Yield Reporting in Lab Reports . Always remember to present your yields and percent yields in the Results Tables. Base the percent yield on the theoretical yield. (Not on the "expected yield". Please note that the theoretical yield is never the "expected yield" as we never expect 100% yield in a chemical reaction.).
