Question

To prepare 0.1M KMno4 solution in 250ml flask.the mask of kmno4 required is

Answer 1

Answer:

Molarity = mass of KMnO4 * 1000 / Molecular Weight of KMnO4 * Vol(ml)

0.1= mass of KMnO4 * 1000 / 158 * 250

mass of KMnO4 = 0.1 * 158 * 250/1000

                           = 3950/1000

                           = 3.95 gm

This is the ans of your question.
