Show the relation between the osmotic pressure of the solutions prepared in 1 liter water by dissolving 10 gram glucose (P_(1)), 10 gram urea (P_(2)) and 10 gram Sucrose, (P_(3)) respectively.

Answer»

`P_(2)GT P_(1)gt P_(3)`
`P_(2)gt P_(3)gt P_(1)`
`P_(1)gt P_(2)gt P_(3)`
`P_(3)gt P_(2)gt P_(1)`

SOLUTION :In equal volume of solution = mole = `(W)/("molecular WEIGHT")` so, as the molecular weight less, the no. of mole is more and HENCE osmotic pressure is also more.
