Chemistry

89.7%

Explanation:

Percentage yield is the ratio of the actual yield of a product to the theoretical yield of a product expressed as a percentage.

Percentage yield = $\frac{actual yield}{theoretical yield}$ x 100

Given,

Actual yield of a product = 2.80 g

Theoretical yield of a product = 3.12 g

Percentage yield = $\frac{2.80 g}{3.12 g}$ x 100 = 89.7 %
