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? Chemistry Solutions Molarity 1 Answer Dr. Hayek May 3, 2016 Answer: 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# Related questions what is the molarity of 20.0 ml of a KCl solution that reacts completely with 30.0 ml of a 0.400 M ...
