The normal freezing point of a certain liquid X is 7.90 °C, but when 9.4 g of alanine (C,H,NO,) are dissolved in 200. g of X the solution freezes at 4.0 °C instead. Use this information to calculate the molal freezing point depression constant K, of X. Be sure your answer is rounded to the correct number of significiant digits. °C·kg K, = 0 mol
