x g of non-electrolytic compound (molar ...

`x g` of non-electrolytic compound (molar mass =200) is dissolved in `1.0 L` of `0.05 M NaCl` solution. The osmotic pressure of this solution is found to be `4.92 atm` at `27^(@)C`. Calculate the value of `x`. Assume complete dissociation of `NaCl` and ideal behaviour of this solution.

A

`16.52g`

B

`24.032g`

C

`19.959g`

D

`12.35g`

Text Solution

Verified by Experts

The correct Answer is:
C
(i) ForNaCl : `pi=iCRT=2xx0.05xx0.0821xx300=2.463` atm
(ii) For unknown compound,`pi=CRT=(x)/(200)xx0.0821xx300=0.1231xx` atm
Total osmotic pressure `pi=pi_(1)+pi_(2)`
`4.92=2.463+0.1231x`
`x=19.959g`
