1 m aq. Solution of a salt shows elevation in boiling point equal to 3 times of its `K_(b)`. Determine
(i) Freezing point of solution
(ii) Osmotic pressure at `27^(@)C`

Explanation

`Delta T_b=i=k_b times m`
`implies 3K_b=I times k_b times 1`
`implies i=3`
`DeltaT_l=I times k_1 times m implies 3 times 1.86 times 1=5.58^@C`
or `T_l=-5.58^@C`
`pi=iCRT=3 times 1 times 0.0821 times 300`
