Answer:
The percent yield is 42.52%.
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 :
[tex]\text{Percent yield}=\frac{\text{Actual yield}}{\text{Theoretical yield}}\times 100[/tex]
Now put all the given values in this formula, we get:
[tex]\%(yield)=\frac{5.4 g}{12.7 g}\times 100=42.52\%[/tex]
The percent yield is 42.52%.
