Since it is not my question I have nothing to lose :)), I'll let you into the hall of creditfame tonight. Of course many on here do, so its not really definitive, its just a birds of a feather kind of relation. So, the equivalent weight of K M n O X 4 is molecular weight 5 When a purple solution of the oxidizing agent KMnO4 is added to an alkene, the alkene is oxidized to a diol and the KMnO4 is converted to brown MnO2. pat, There is a good dog :), http://web2.0calc.com/questions/wrap-lantern-thursday-14-1-16#r1. In other words, the mole fraction of O is 1/6, the mole fraction of Mn is 1/6, and the mole fraction of O is 2/3.
