The theoretical yield of zinc oxide in a reaction is 486 g. what is the percent
yield if 399 g is produced?
a. 29.6%
b. 4.93%
c. 82.1%
d. 122%

Sagot :

82.09% is the percent yield if 399 g is produced. Hence, option  C is correct.

What is the percent yield?

Percent yield is the percent ratio of actual yield to the theoretical yield.

Given data:

Actual yield = 399 g

Theoretical yield = 486 g

%Yield = [tex]\frac{Actual \;Yield \;X \;100 }{Theoretical \;Yield}[/tex]

%Yield = [tex]\frac{399 gX \;100 }{486 g \;Yield}[/tex]

= 82.09%

82.09% is the percent yield if 399 g is produced.

Hence, option  C is correct.
