The equation for Percent Yield:

• (theoretical/actual) X 100%

• (actual/theoretical) X 100%

• (actual - theoretical)/ theoretical X 100%

Complete the equation for the percent yield of a chemical reaction:
Percent yield=(________)÷(________)×100%

• actual yield; theoretical yield

• theoretical yield; actual yield
