Calculate the osmotic pressure of `20%` (wt.`//` vol.) anhydrous `CaCl_(2)` solution at `0^(@)C` assuming `100%` ionisation.

Calculate the osmotic pressure of 20% (wt. // vol.) anhydrous Ca(NO_(3))_(2) solution at 0^(@)C assuming 100% ionisation.

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.
