Question

An aqueous solution freezes at 272.4 K, while pure
water freezes at 273.0 K. Determine
32 (i) the molality of the solution
---(ii) boiling point of the solution
(iii) lowering of vapour pressure of water at 298 K.
(Given : Kp=1.86 K kg mol-', Kb =0.512 K kg mol-
and vapour pressure of water at 298 K = 23.756 mm
Hg)​
