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

if you mean hydrogen and oxygen then water is the product

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions
