Permanganato potasico [Spanish] HSDB 1218. Diversey Diversol CX with Arodyne The way you want to find the percent composition would be by breaking down the problem like so: K = atomic mass of K which is 39.098 Mn = atomic mass of Mn which is 54.938 O = atomic mass of o which is 15.999 Then you want to add 39.098 + 54.938 + 15.999 and you get 110.035 which is the molar mass for KMnO Therefore, the mass percentage of oxygen in potassium permanganate ({eq}KMnO_4 {/eq}) is 40.496 %.
