A 0.5 percent solution of potassium chloride was found to freeze at \( -0.24^{\circ} \mathrm{C} \). The percentage dissociation of potassium chloride is . (Nearest integer) (Molal depression constant for water is \( 1.80 \mathrm{~K} \mathrm{~kg} \mathrm{~mol}^{-1} \) and molar mass of \( \mathrm{KCl} \) is \( 74.6 \mathrm{~g} \mathrm{~mol}^{-1} \) )
