The osmotic pressure of a dilute solutio...

The osmotic pressure of a dilute solution of a compound XY in water is four times that of a solution of 0.01 M `BaCl_(2)` in water. Assuming complete dissociation of the given ionic compounds in water, the concentration of XY (in `"mol" L^(-1)`) in solution is:

A

`4xx10^(-2)`

B

`6xx10^(-2)`

C

`4xx10^(-4)`

D

`16xx10^(-4)`

Text Solution

Verified by Experts

The correct Answer is:
B
We know, `pi=iCRT, pi_(xy)=4pi_(BaCl_(2))`
`therefore 2[XY]=4xx(0.01)xx3`
`[XY]=0.06`
`=6xx10^(-3)"mol/L"`
