Astudent isolated 16 g of a compound following a procedure
that would theoretically yield 39 g. what was his percent yield?

41.03%

Explanation:

From the question;

Actual yield is 16 g Theoretical yield is 39 g

We are required to determine the percent yield

We need to know that the percent yield is given by;% yield = (Actual yield ÷ theoretical yield) × 100

Thus, in this case;

% yield = (16 g ÷ 39 g)× 100

            = 41.03%

Thus, the percent yield is 41.03%

The answers is a nuclear changes

There is no reason to think the results are biased or not conducted properly but you should not assume the results are correct just because they were done in a laboratory so the answer would be c. it is likely to be reliable because the results support the conclusion presented.
