A student measures a pressure increase of 0.25 atm while collecting the H2 gas products from the reaction of Mg with HCl. The theoretical pressure change is 0.29 atm. What is the % yield

Respuesta :

Answer: Thus the % yield is 86.2%

Explanation:

Percentage yield is the ratio of actual change to the theoretical change in terms of percentage.

The given reaction is :

[tex]Mg+2HCl\rightarrow MgCl_2+H_2[/tex]

To calculate the percent yield :

[tex]\%\text{ yield of reaction}=\frac{\text{Actual yield}}{\text{Theoretical yield}}\times 100[/tex]

Given : Actual pressure increase = 0.25 atm

Theoretical pressure change = 0.29 atm.

[tex]\%\text{ yield of reaction}=\frac{0.25}{0.29}\times 100=86.2\%[/tex]

Thus the % yield is 86.2%

Answer:

86%
