What is the percent yield of ferrous sulfide if the actual yield is 220.0 g and the theoretical yield is 275.6 g?
actual yield
use %yield =
theoretical yield x 100
12.5%
55.6%
79.8%
o 87.9%

The answer is:

The third option, 79.8%

To calculate the percent yield we need to divide the actual yield by the theoretical yield, and then, multiply it by 100 in order to find the percent.

So, we from the statement we know the following information:

Let's use the following formula and substitute the given information:

Hence, we have that the correct option is the third option, the percent yield is 79.8%.

Have a nice day!

i do not get it   at all

you need to have a picture of the atom that way we can answer it
