#1: the theoretical yield of a reaction is 5.00 moles of potassium permanganate (kmno4). if the reaction actually produces 695.2 g kmno4, what is the percent yield of the reaction?

a. 78%

b. 83%

c. 88%

d. 120%

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
