Question

What is the molarity of a solution with 0.2 moles of potassium permanganate (kmno4 dissolved in enough water to make a 500.0 ml solution?

Answer 1

Data:


Molarity: M


n = 0.2 moles


V = 500.0 ml = 0.5 liter


Fórmula:


M = n / V


M = 0,2 mol / 0,5 liter = 0,4 mol/liter = 0,4 M


Answer: M = 0,4 M
