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 ?

Answer»

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

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