WebOct 13, 2024 · Now we can determine how many moles of oxygen we have out of the total moles: 4 oxygen for every 1 KClO 4 so we can multiply our total moles of KClO 4 by 4 to obtain the moles of oxygen: (4 moles O / 1 moles KClO 4) × 3.25 × 10 -2 moles KClO 4 = 0.130 moles O. We can convert our moles of oxygen into atoms using Avogadro's number: WebIndustrially, KM n O 4 is prepared using manganese dioxide. As stated above, this chemical compound is reacted with alkali metal hydroxide which is potassium hydroxide. The mixture is then heated in the air at high temperatures. When the reaction is completed potassium manganate is formed. 2 MnO 2 + 4 KOH + O 2 → 2 K 2 MnO 4 + 2 H 2 O.
