The osmotic pressure of urea solution at `10^(@)C` is 200mm. It becomes 105.3 mm when it is diluted and temperature raised to `25^(@)C`. The extent of dilution is

Text Solution

Verified by Experts

The correct Answer is:
2
`pi = CRT (pi_(1))/(pi_(2)) = (C_(1)T_(1))/(C_(2)T_(2))`
`(200)/(105.3) = (C_(1))/(C_(2)) xx (283)/(298)`
`(C_(1))/(C_(2))=2`
