An aqueous solution is \( \mathbf{1 . 1 2 1} \) molal in silver nitrate. It has a freezing point of \( \mathbf{- 2 . 8 6 2}{ }^{\circ} \mathrm{C} \). Determine the effective number of particles arising from each \( \mathrm{AgNO}_{3} \) formula unit in this solution. For water, \( \mathrm{Kfp}=1.86^{\circ} \mathrm{C} / \mathrm{m} \).
