What is the osmotic pressure of `12%` solution of can sugar (mol.wt. 342) at `17^(@)C`

A

`2.42"atm"`

B

`4.33"atm"`

C

`8.35"atm"`

D

`16.30"atm"`

Text Solution

Verified by Experts

The correct Answer is:
C
12 g of sugar is dissolved in 100 mL water.
`:.` 342g of sugar is dissolved in
`(100)/(12)xx342=2850mL=2.85L`
`:.V=2.85LrArrpiV=RT`
`"or "pi=(RT)/(V)=(0.082xx290)/(2.85)=8.343"atm"`
`~=8.35"atm"`
