A student calculates that they should produce 12.5g of MgO in lab. After the lab, the weighs the MgO, and finds that he made 10.8g of MgO. What is his theoretical yield?

10.8g
|
|
|
12.5g
|
|
|
86.4
|

None of the above

Explanation:
Detailed explanation-1: -The actual yield divided by present yield Times 100%. Substituting given optimal yield here is 12.4g, Divided by the percent yield, which is % 25 very sad, Times 100%. This is equals to 49 16 grubs and that S. D. First choice thing.
Detailed explanation-2: -Balance the reaction. Identify the limiting reagent, which is the reagent with the fewest moles. Divide the fewest number of reagent moles by the stoichiometry of the product. Multiply the result of Step 3 by the molecular weight of the desired product. 30-Dec-2022
