Question

If the theoretical yield of LiOH in the reaction below is 47.4 g and the actual yield is

18.9 g, calculate the percent yield.

Given: Li2O+ H2O – 2 LiOH

Answer 1

The percentage yield of LiOH is 39.9%

Step-by-step explanation:

From the question given above, the following data were obtained:

Theoretical yield = 47.4 g

Actual yield = 18.9 g

Percentage yield =?

The percentage yield of LiOH can be obtained as follow:

Percentage yield = Actual yield / Theoretical yield × 100

Percentage yield = 18.9 / 47.4 × 100

Percentage yield = 1890 / 47.4

Percentage yield = 39.9%

Therefore, percentage yield of LiOH is 39.9%
