Solution:

The molar mass of KIO3 is 214 g/mol.

Therefore,

(96.3 g KIO3) × (1 mol KIO3 / 214 g KIO3) = 0.45 mol KIO3


Molarity is defined as number of moles of solute dissolved in 1 L of solution.

Therefore,

Molarity = (0.45 mol / 0.3 L) = 1.5 mol/L

Molarity = 1.5 mol/L


Answer: The molar concentration of the solution is 1.5 mol/L
