Question

The theoretical yield of a reaction is 75.0 grams of product and the actual yield is 42.0g. what is the percent yield? 178 31.5 75.0 56.0 none of the above

Answer 1

Use the formula:

                                   actual yield
Percent yield, % = --------------------------- x 100
                                theoretical yield

Percent yield, % = (42.0 g / 75.0 g) * 100 = 56.0

Answer: 56.0
