Question

18.7 grams if is dropped into a solution containing excess copper phosphateWhen the reaction is completed, 8.7 grams of copper formed. Theoretically 86,04 grams of copper should be formed. What is the percent yield?

Answer 1

Answer:

$Y=10\%$

Explanation:

Hello there!

In this case, according to the given information, whereas it is given both the theoretical and actual yield of copper metal, which are 86.04 g and 8.7 g respectively.

Next, since the percent yield is given by:

$Y=\frac{actual}{theoretical}*100\%$

Next, we plug in the aforementioned yields to obtain:

$Y=\frac{8.7g}{86.04g}*100\%\\\\Y=10\%$
