Greeley [361]

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

<h3>What is molarity? </h3>

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

Molarity = mole / Volume

<h3>How to determine the molarity </h3>
  • Mole of KMnO₄ = 35 moles  
  • Volume = 500 mL = 500 / 1000 = 0.5 L
  • Molarity =?

Molarity = mole / Volume

Molarity = 35 / 0.5

Molarity = 70 M
