The `1.25` mola sucrose solution at temperature `60^(@)` has a density of `0.1142 g//ml`, then the osmotic pressure of solution will be

A

`2.5`

B

`3.5`

C

`2.0`

D

`4.0`

Text Solution

Verified by Experts

The correct Answer is:
1
`m=(1000M)/(1000d-m_(1)M)`
`1.25=(1000M)/(100xx0.1142-343M)`
`M=0.9mol//L`
`T=MRT" "rArr" "0.09xx(1)/(12)xx298=2.49~=2.5`
