Chemistry - Liquid Solution Question with Solution | TestHub

After sufficient time osmotic pressure of all solution will become same.

as T is same i.e. molar concentration should be same, for this ratio of volume should be the same as that of ratio moles.

Urea : KCl : ${\mathrm{AlCl}}_3$

20 m moles 30 m moles 40 m moles

Total volume (300 ml) should be divided in 2 : 3 : 4

$$\begin{array}{rlr}& {\mathrm{V}}_{\text{urea }}=\frac{2}{9}\times 300=\frac{200}{3}\mathrm{ml}& {\mathrm{V}}_{\mathrm{KCl}}=\frac{3}{9}\times 300=100\mathrm{ml}.\end{array}$$
