Osmotic pressure of a sugar solution at ...

Osmotic pressure of a sugar solution at `24^(@)C` is 2.5 atmosphere .Determine the concentration of the solution in gram mole per litre.

A

`0.0821"moles/litre"`

B

`1.082"moles/litre"`

C

`0.1025"moles/litre"`

D

`0.0827"moles/litre"`

Text Solution

Verified by Experts

The correct Answer is:
C
Here it is given that
`pi=205"atm,"" T"=24+273=297"A"^(@),"S"=0.0821"lit.atm. " "deg"^(-1)"mol"^(-1),"C"=?`
We know that `pi="CST "or "C"=pi/"ST"=2.5/(0.0821xx297)=0.1025" mole/litre"`
