A $\displaystyle 0.0020$ m aqueous solution of an ionic compound $\displaystyle \mathrm{Co}\left(\mathrm{NH}_3\right)_5\left(\mathrm{NO}_2\right) \mathrm{Cl}$ freezes at $\displaystyle -0.00732^{\circ} \mathrm{C}$. Number of moles of ions which $\displaystyle 1$ mol of ionic compound produces on being dissolved in water will be ( $\displaystyle \mathrm{k}_{\mathrm{f}}=-1.86^{\circ} \mathrm{C} / \mathrm{m}$ )
Official answer
(2)
$\displaystyle 2$
