Which formula can be used to calculate the actual yield?
(percent yield × theoretical yield) ÷ 100
(percent yield ÷ theoretical yield) × 100
(theoretical yield ÷ percent yield) × 100
(theoretical yield × amount of reactants) ÷ 100

(Percent yield × theoretical yield) ÷ 100.

Explanation:

∵ percent yield of the reaction = [(actual yield)/(theoretical yield)] x 100.

∴ actual yield = [(percent yield of the reaction) x (theoretical yield)]/100.

So the right choice is: (Percent yield × theoretical yield) ÷ 100 .
