#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%

Respuesta :

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
