The theoretical yield is the maximum amount of product that can be pro. In this experiment the percent yield is 767 yield which shows that it is almost fully pure and contains lesser impurities. Dividing by the fraction used in the recrystallization An alternative way to calculate this when not all the crude is purified is to consider the formation of crude product and purification to be individual steps then the overall yield is obtained by multiplying the yields of the two steps.
Then your percent recovery is 70 710 x 100.
Percent yield 243 g 296 g 100 0894 92 Calculate Percent Yield. When the solution cools 053 g of this 5 g will not come out of solution. Calculate in the usual way then divide by the fraction used for recrystallization. In a recrystallization reaction the original substance is recrystallized after which its recovery value can be computed.
