What is the volume of solution containing 1g mole of sugar that will give rise to an osmotic pressure of 1atmosphere at `0^(@)C` ?

Text Solution

Verified by Experts

The correct Answer is:
22.4 L
`pi=1 atm, n=1"g mol",R=0.0821"L atm K"^(-1)mol^(-1),T=0^(@)C=0+273=273 K`
`pi=n/VRTor V=n/piRT`
`V=((1"gmol")xx(0.0821"L atm K"^(-1)mol^(-1))xx(273 K))/((1"atm"))=22.4 L`.
