Question

If the theoretical yield of the reaction below corresponds to 25.3 g and the percent yield of the reaction is known to be reproducibly 81.1%, calculate the actual yield. given: li2o + h2o → 2 lioh 81.1 g 48.9 g 20.5 g 45.8 g none of the above

Answer 1

The actual yield is computed by multiplying the theoretical yield by the decimal equivalent of the given yield of reaction.
That is,
Actual yield = (Theoretical Yield) x (Percent Yield of reaction)
Actual yield = (25.3 g) x (0.811)
Actual yield = 20.51 g

Hence, the actual yield is approximately 20.5g and the answer is the third choice.
