A student isolated 25 g of a compound following a procedure that would theoretically yield 81 g. What was his percent yield?

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

30.9 % to the nearest tenth.

Explanation:

That is (25/81) * 100

= 30.86%.
