Question

7 Be + 2 HCl →BeCl2+ H2

My theoretical yield of beryllium chloride was 12.7 grams. If my actual
yield was 5.4 grams, what was my percent yield?

Answer 1

The percent yield is 42.52%.

Step-by-step explanation:

Theoretical yield of beryllium chloride = 12.7 g

Actual yield of the beryllium chloride = 5.4 g

The formula used for the percent yield will be :

`\text{Percent yield}=\frac{\text{Actual yield}}{\text{Theoretical yield}}* 100`

Now put all the given values in this formula, we get:

`\%(yield)=(5.4 g)/(12.7 g)* 100=42.52\%`

The percent yield is 42.52%.
