Question

What is the molarity of a solution with 0.2 moles of potassium permanganate (`KMnO_4`) dissolved in enough water to make a 500.0 mL solution?

Answer 1

The solution is `0.4M`.

Explanation:

The molarity of a solution is found by: `C_M=n/V` where,

`n` is the number of mole of solute and `V` is the volume of the solution.

Therefore, `C_M=(0.2mol)/(0.5000L)=0.4M`
