Osmotic pressure of a urea solution at 1...

Osmotic pressure of a urea solution at `10^(@)C` is 500 mm. Osmotic pressure of the solution become 105.3 mm. When it is diluted and temperature raised to `25^(@)C`.The extent of dilution is

A

`6` times

B

`5` times

C

`7` times

D

`4` times

Text Solution

Verified by Experts

The correct Answer is:
B
`piV=nRT`
`(500V_(1))/(105.3V_(2))=(nRxx283)/(nRxx298),rArr(V_(1))/(V_(2))=(1)/(5)so V_(2)=5V_(1)`
