Answer:You have to multiply the theoretical by the percent yield to get the actual yield. You perform an experiment and theoretically you get all the yield, but that's impossible as nothing is 100% efficient so you multiply the theoritcal times the efficiency ratio. 38%* 332.5= actual. It's like mpg in a car gasoline has a lot of energy, but some cars have better efficiency. Chemistry is many times never 100% effecient.
