Question

15 grams of HCl should theoretically produce 0.42 grams of H2. The reaction actually produced 0.15 grams of H2. What is the percentage yield of H2?
Steps to solution please

Answer 1

Answer:

35.7%

Explanation:

The percent yield is calculated by the formula:

[(actual yield) / (theoretical yield)] * 100

In this case, the actual yield is 0.15 grams, and the theoretical yield is 0.42 grams. So, putting these values into the equation, we have:

$\frac{0.15}{0.42} *100=0.357*100=35.7$

Thus, the percent yield of $H_2$ is 35.7%.

Hope this helps!
