What's the definition of M? It's molarity = mols/L. You know L and M; you don't know mols so solve for mols you need.
How do you get grams from mols? That's mols = grams/molar mass. You know molar mass and mols, solve for grams.
Place that many grams KMnO4 in a 100 mL volumetric flask, add a little water, swirl until all is dissolved, add DI water to the mark on the volumetric flask, mix thoroughly, stopper.
That will prepare 100 mL of 0.1M KMnO4 solution.
Describe the procedure to prepare this solution:
100 mL of a solution 0.1 M of KMnO4
Help? I don't understand what this implies.
