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

and molecular weight of KMnO4 = (39) + (55) + (4 x 16) = 158
Hence, No of moles = 100/158 = 0.632

How many moles of KMnO4 are present in 75.0 mL of a 0.0950 M solution?
Molarity = moles of solute/Liters of solution ( 75.0 ml = 0.075 Liters ) Algebraically manipulate, moles of solute = Liters of solution * Molarity Moles KMnO4 = (0.075 Liters)(0.0950 M) = 7.13 X 10 -3 moles KMnO4 ------------------------------------
Chemical symbol for permanganate?
The formula for potassium permanganate is KMnO4
What is the chemical formula for Condys Crystals?
Formula: KMnO4
What is the mass of 2.55 mol of KMnO4?
Number of moles= Mass/molar mass (g/mol) Hence Mass= mol × molar mass Mol=2.55 Molar mass of KMnO4= 39+55+(16×4)= 158g/mol Where K=39, Mn=55 and O =16 Hence Mass of KMnO4 in 2.55 mols of the compound= 2.55×158= 402.9g.
Why does alkene reacts kmno4?
KMnO4 will react with compounds having unsaturation (double bond or triple bond). Since alkenes have double bond, it will react with KMnO4 and decolourize dilute KMnO4 solution.
What is molarity of a solution that contains 0.798 g KMnO4 in 50.0 mL solution?
The molar mass of KMnO4 is 158,3415 g.The molarity of this solution is 0,1 M.

In manufacture of potassium permanganate by electrolysis of k2mno4 what should be the equivalent weight of kmno4 how much kmno4 will be produced by 96478 coulombs or one farady?
Equivalent weight of KMnO4 is equal with molar weight of KMnO4. The some is and for K2MnO4, K2MnO4 - e +OH- --------- KMnO4 + KOH In general, Equivalent weight = Molar weight / Number of electrons that take or give one molecule Equivalent weight of KMnO4 = Molar weight of KMnO4 / 1
