Astudent isolated 25 g of a compound following a procedure that would theoretically yield 81 g. what was his percent yield?

The student's percent yield is 30.86%

From the question,

We are to determine the percent yield of the student

Percent yield can be calculated by using the formula

From the question,

Actual yield = 25 g

Theoretical yield = 81 g

Putting the parameters into the formula, we get

Percent yield =

Percent yield =

Percent yield = 30.86%

Hence, the student's percent yield is 30.86%

The answer to your question is: yield = 30.9%

Explanation:

Data

mass of compound isolated = 25 g

theoretical mass = 81 g

Formula

% yield =  mass of compound isolated / theoretical mass  x 100

% yield = 25 / 81 x 100

% yield = 30.9
