Question

An aqueous solution freezes at 272.4k while purewater freezes at 273k Determinei) Molality of soln ii) Bp of the soln (Kf=1.86,Kb= 0.512) ​

Answer 1

Answer:

An aqueous solution freezes at 272.4 K while pure water freezes at 273 K. Determine the boiling point of the solution.

[Given : K

f

=1.86 K kg mol
