An aqueous solution of urea has a freezing point of `-0.52^(@)C`. Assuming molarity same for the solution, the osmotic pressure of solution at `37^(@)C` would be : `(K_(f)` of `H_(2)O=1.86 K` molarity`.^(-1)`)

A

`7.9 atm`

B

`7.1` atm

C

`6.9 atm`

D

`10.2 atm`

Text Solution

Verified by Experts

`m=(DeltaT_(f))/(K_(f))=0.52/1.86=0.280 =M`
Also `pi=mRT`
`=0.28xx0.0821xx310`
`=7.1 atm`
