What is the precent yield if the actual yield is 25g and 100g should have formed?

Percent yield is 25%

Explanation:

Information given is

Actual yield is 25 g

But the yield should be 100 g

The percent yield is defined as the ratio of the actual yield and the predicted yield it means that out of the predicted yield what percentage of the actual yield is obtained

∴ Percent yield = (Actual yield ÷ Predicted yield) ×  100

In case of the given problem the percent yield will be

(25÷100) × 100 = 25%

∴ Percent yield = 25%
