At 273 K temperature, if 10 gm glucose (...

At 273 K temperature, if 10 gm glucose `(p_(1))`, 10 gm urea `(p_(2))` and 10 gm sucrose `(p_(3))` is dissolved in 250 mL of water, then what is the correct relation of osmotic pressure for them ?

A

`p_(1)gt p_(2)gt p_(3)`

B

`p_(3)gt p_(2)gt p_(1)`

C

`p_(2)gt p_(1)gt p_(3)`

D

`p_(2)gt p_(3)gt p_(1)`

Text Solution

Verified by Experts

The correct Answer is:
C
`p=(wRT)/(MV)` Where, `(wRT)/(V)` is constant and so, `p prop (1)/(M)`
So, `p_(2)gt p_(1)gt p_(3)`.
