The freezing point of a 0.05 molal solution of a non electrolyte in water is (Kf = 1.86 k kg mol-1)
-0.93 oC
-1.86 oC
-0.093 oC
0.93 oC
Tf = Kf x m = 1.86 x 0.05 = 0.093oC
Tf = 0 - 0.093 = -0.0930C
Molal depression constant for water is 1.86°C. The freezing point of a 0.05 molal solution of a non-electrolyte in water is
The freezing point of 1 molal NaCl solution assuming NaCl to be 100% dissociated in water is Kf = 1.86 k kg mol-1)
