Calculate the % yield if the amount of alum obtained was 18.28 g and the expected amount was 19.93 g.

Answer : The percent yield will be, 95.06 %

Explanation :  Given,

Actual yield of the reaction = 18.28 g

Expected yield of the reaction = 19.23 g

The formula used for the percent yield will be :

Now put all the given values in this formula, we get:

Therefore, the percent yield will be, 95.06 %
