Question

An aqueous potassium iodate ( KIO 3 ) solution is made by dissolving 587 grams of KIO 3 in sufficient water so that the final volume of the solution is 5.00 L. Calculate the molarity of the KIO 3 solution.

Answer 1

[KIO₃] = 0.548 M

Step-by-step 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
