1 mole of liquid A and 9 moles of liquid B are mixed to form a solution. If `"P"_("B")^(@)=400"mm"` of Hg and `"P"_("A")^(@)=20 "mm"` of Hg at a temperature 'T' and normal boiling point of liquid B is 300K then answer the questions that follow.
Given data: `"K"_("b")=2.7"K kg mol"^(-1),` Molar mass of B=100
If 'A' is assumed to be perfectly non volatile then what will be normal boiling point of the solution.

Options

A. `300`
B. `300.3`
C. `303`
D. `300.03`

Answer

C
