Percent Yield. Most reactions do not go to completion, and so the actual yield is less than the percent yield. The percent yield is calculated as % YIELD = ACTUAL YIELD (this must be measured!) *100 . THEORETICAL YIELD (which is what you calculated) In other words, ,ost reactions aren’t produced as efficiently as you predicted.
