B83%

C88%

D120%

The formula actual yield /
theoretical yield is used to calculate the percent yield of a reaction.
This value is a measure of how much product is produced relative to the what is
supposed to be produced. We calculate as follows:

Percent yield =  actual yield / theoretical yield x 100
Percent yield = 695.2 g ( 1 mol / 158.034 g) / 5 x 100
Percent yield = 88% <------OPTION C
