Calculate the osmotic pressure `0.2%` (wt.//vol) of anhydrous `CaCl_(2)` solution at `27^(@)C` assuming `90%` ionisation of `CaCl_(2)`. Also report the temperature at which this solution will boil and freeze if `K_(b)` and `K_(f)` for water are `0.51` and `1.86K` molality`^(-1)`. If vapour pressure of water at `27^(@)C` is `24mm` , find out the vapour pressure of his solution. Assume molarity and molality same.

A
