Scientist A produces 83.67 g KMnO4 while Scientist B produces 81.35 g KMnO4. What is the percent yield for Scientist A? What is the percent yield for Scientist B? You must show all work to receive full credit. The equation for the production of potassium permanganate is as follows: 2 MnO2 + 4 KOH + O2 → 2 KMnO4 + 2 KOH + H2
