In MnO 2, the oxidation state of Mn is + … This compound is also known as Potassium Permanganate. Completing the CAPTCHA proves you are a human and gives you temporary access to the web property. To convert grams to moles, the molecular weight of the solute is needed. An equivalent weight is equal to the molecular weight divided by the valence (here it gets a little tricky, for acids ands bases it refers to the number of H+ or OH-, in salts it must be expressed which ion is meant unless the ratio is 1:1). If the formula used in calculating molar mass is the molecular formula, the formula weight computed is the molecular weight. Thus, the equivalent mass = molecular mass/1 = molecular mass = M Hence, the equivalent mass of KMnO4 is M when it converts over to K2MnO4. Equivalent weight = molecular weight/valency factor.

Molar mass of KMnO4 = 158.033949 g/mol. lets see the reaction first, 2KMnO4 +10FeSO4 . Almost all applications of KMnO4 exploit its oxidizing properties. The molecular weight of this is 158g and as during reduction this accepts five electrons.. 6. ›› KMnO4 molecular weight. Its equivalent weight when it is oxidized by KMnO4 KMnO4, in acidic medium is: Latest answer posted June 29, 2011 at 6:04:17 PM The formula weight is simply the weight in atomic mass units of all the atoms in a given formula. You may need to download version 2.0 now from the Chrome Web Store. Each substance has a respective molecular weight … The effect of molecular weight on the rate of diffusion was determined using the Agar-water Gel Test. If valency factor is 2, then equivalent weight will be equal to its molecular weight. Latest answer posted June 29, 2011 at 6:04:17 PM common chemical compounds. If you are at an office or shared network, you can ask the network administrator to run a scan across the network looking for misconfigured or infected devices. Molar Mass: Molar mass is the number of grams of a substance that equals to one mole or 6.02 x 10 23 molecules, also known as Avogadro's number. The atomic weights used on this site come from NIST, the National Institute of Standards and Technology.
