Formula weight of KMnO4 is 158.04. The equivalent weight depends on the reaction involved. In acidic media it is (formula weight) /5, in neutral although this is more difficult to control it is the formula weight.
Knowing which type it is usually acidic as it is easier, you will need 158.04/5 X 0.2 = 6.32g.
Sulfuric acid is usually added in the titration to ensure the correct oxidation reaction is carried out.
Also note KMnO4 is not considered a primary standard so you should really filter the solution to remove any MnO2 caused by oxidation of organic impurites in the water you are using, and standardise the solution by titration against say oxalic acid. K

What mass of KMnO4 is required to prepare 3.00 liters of a 0.05253 M solution of KMnO4?
24 g
How many grams of KMnO4 should be used to prepare 2L of a 5M solution?
To prepare 2L of a 5M solution, you should put in 4.6575grams of KMnO4. It is important to make sure that you add them in that order. K should be added first, then Mn.
How do you prepare 0.05 N solution of KMnO4?
Dissolve 1,65 g potassium permanganate for analysis in 1 L demineralized water.
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.
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 KNMO4 solution?
There is no such solution.You probably mean KMnO4 which is Potassium Permanganate solution.
How do you prepare 100 ml of 1 in 1000 KMnO4?
700gram = 0.7 kilogram
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 ------------------------------------
Which solution may be used to disinfect water?
a dilute aqueous solution of KMnO4 may be used.
You have .2 n kmno4 which you have to dilute it to 0.05n kmno4 how can you dilute that?
4 x. Take 25ml of 0.2 M solution and dilute to 100ml.

What happen when ethanol is heated with alkaline kmno4 solution?
When ethanol is added to alkaline KMno4 solution, the ethanol gets oxidised to ethanoic acid due to nascent oxygen. KMno4 is an oxidising agent. thus when we first add alkaline Kmno4 to ethanol, the pink colour of the Kmno4 vanishes, as it is being used up for the oxidation process. however. when all of the ethanol has been oxidised into ethanoic acid, and we keep adding Kmno4, the colour returns, as there is no more ethanol left to oxidise.
