Given a certain quantity of reactant, you calculate that a particular reaction should produce 55g of a product. When you perform the
reaction, you find that you have produced 63g of product. What is
the percent yield?

Percent yield =  114.5%

Explanation:

Given data:

Calculated amount of product/ theoretical yield = 55 g

Actual amount of product after performing reaction = 63 g

Percent yield = ?

Solution:

Formula:

Percent yield = ( actual yield / theoretical yield )× 100

by putting values,

Percent yield = (63 g/ 55 g)× 100

Percent yield =  114.5%
