Question

The theoretical yield of zinc oxide in a reaction is 486 g. what is the percent

Answer 1

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 = $\frac{Actual \;Yield \;X \;100 }{Theoretical \;Yield}$

%Yield = $\frac{399 gX \;100 }{486 g \;Yield}$

= 82.09%

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

Hence, option  C is correct.
