in the reaction between co and fe304 the theoretical yield in an experiment is calculated to be 47.2 g fe. when a careless chemistry student carries out the experiment, the actual yield is 42.9 g fe. calculate the percentage yield.



Answer :

The percentage yield for the reaction is 99.88% .

The formula for the percentage yield is mentioned below;

Percent yield = actual yield / theoretical yield x 100%           equation 1

Theoretical yield = 47.2 g

Actual yield = 42.9 g

If the theoretical yield of the reaction is 47.2 g Fe, we assume it as 100%, then

47.2 g Fe -----------------> 100 %

Using unitary method , we can also write this as

1g Fe ----------------->  (100/47.2) %

42.9g Fe ----------------->  (100/47.2) × 42.9 %

42.9g Fe ----------------->  99.88 %

Or using equation1 , we can simply write this as

Percent yield = (42.9/47.2)×100 = 99.88%

Thus, we can say  99.88 % is the percentage yield for the reaction.
