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

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:

Thus, the percent yield of is 35.7%.

Hope this helps!
