Yes, we can dissolve 35 moles of KMnO₄ into 500 mL of water to give a molarity of 70 M

What is molarity?

Molarity is defined as the mole of solute per unit litre of solution. Mathematically, it can be expressed as:

Molarity = mole / Volume

How to determine the molarity

  • Mole of KMnO₄ = 35 moles  
  • Volume = 500 mL = 500 / 1000 = 0.5 L
  • Molarity =?

Molarity = mole / Volume

Molarity = 35 / 0.5

Molarity = 70 M

We can not dissolve 35 moles of potassium permanganate into 500 ml of water as it produces the solution with higher molarity than water have.

What is molarity?

Molarity of any solution is define as the number of moles of solute present in per liter of the solvent as:

M = n/V

The molarity of the solvent, water, is the highest for aqueous solutions and molarity of 1000g of pure water in 1 liter is 55.5M

Given that,

  • n = moles of potassium permanganate = 35 moles
  • V = Volume = 500 mL = 500 / 1000 = 0.5 L

On putting values, we get

M = 35/0.5 = 70M

Preparation of this solution is impossible.

Hence, KMnO₄ will not dissolve in the water as it produces solution with higher molarity than water.
