You complete a chemical reaction and recover 79 grams of product. However, you calculate you should have recovered 104 grams of

spin [16.1K]

Percent yield is calculated using:
$percent \: yield = \frac{actual \: yield}{theoretical \: yield} \times 100\%$

Your actual yield is how much you actually had at the end of the experiment = 79g.

Your theoretical yield is how much you calculated you should have gotten in an ideal, perfect experiment = 104g.

So put those values into the equation:
$percent \: yield = \frac{79}{104} \times 100\% = 76\%$
