The osmotic pressure (atm) of `2.22%` (w/v) `CaCl_(2)` solution at `27^(@)C` is (R=0.08L-atm/k-mol)

Text Solution

Verified by Experts

The correct Answer is:
`14.40`
`2.22%w/vimplies22.2gm CaCl_(2)` per litre
`=0.2` moles/litres
For `CaCl_(2)i=3` on ionisation
`pi=iCRT=3xx0.2xx0.08xx300`
`=14.4` atm
