1 gm of polymer having molar mass 1,60,000 gm dissolve in 800 ml water, so calculate osmotic pressure in pascal at `27^(@)C(R=8.314` J/K mole)

A

`0.78`

B

`0.90`

C

`0.50`

D

`1.20`

Text Solution

Verified by Experts

The correct Answer is:
A
`pi =CRT`
`pi =(1)/(1.6xx10^(5))xx(8.314xx300)/(800xx10^(-8))=0.78`
