Among the given solutions of potassium permanganate (KMnO4), which one has the highest concentration of water in it?

Solution D has the highest concentration of all.

Explanation:

The formula used to calculate molarity:

 .....(1)

Molarity of permanganate solution = 0.1 M

Volume of solution =        (Conversion factor: )

Putting values in equation 1, we get:

Molarity of permanganate solution = 0.01 M

Volume of solution =

Putting values in equation 1, we get:

Molarity of permanganate solution = 2 M

Volume of solution =

Putting values in equation 1, we get:

Molarity of permanganate solution = 2.5 M

Volume of solution =

Putting values in equation 1, we get:

The solution having the highest number of moles will have the highest concentration for the same volume.

Thus, solution D has the highest concentration of all.
