Now that you have the molar mass of the solute, you need to multiply the number of grams of solute in the solution by a conversion factor of 1 mole over the formula weight (molar mass) of the solute. This will give you the number of moles of the solute for this equation. 2010-11-23 · To find gram formula mass (molecular mass) of a molecule you find the atomic mass of K, Mn and 4 atoms of oxygen. Then you add all these number up to get the gram formula mass. For example.

The formula mass of KMnO4 is 158.0Amount of KMnO4 = mass of sample / molar mass = 100/158.0 = 0.633 molThere are 0.633 moles in 100g of potassium permanganate.

The unit for molar mass is g/mol. You can use molar Equivalent weight can be calculated by using the formula. Equivalent weight = Molar mass/number of electrons lost or gained (n) The molecular mass of KMno4 = 158.04g.

Molar Mass: 262.1763. Example Reactions: • MgS + 2 KMnO4 = K2S + Mg(MnO4)2 • 2 KMnO4 + Mg(OH)2 = 2 KOH + Mg(MnO4)2 • Mg(MnO4)2 + K2O = 2 KMnO4 + MgO :: Chemistry Applications:: » Chemical Elements, Periodic Table » Compound Name Formula Search » Moles to Grams Calculator
