    [KIO₃] = 0.548 M

    Explanation:

    Molarity is a sort of concentration which involves moles of solute in 1L of solution.

    Volume of solution 5L

    Mass of solution: 587 g

    Let's convert the mass to moles (mass / molar mass)

    587 g / 214 g/mol = 2.74 moles

    Molarity is mol/L → 2.74 mol / 5L = 0.548 M
