Provide examples of osmotic pressure in daily life.

Arrange the following solutions according to decreasing order of osmotic pressure under similar conditions of temperature,assuming complete dissociation:
$A. 0.2 \ m \ KCl$
$B. 0.3 \ m \ MgSO_4$
$C. 0.1 \ m \ BaCl_2$
$D. 0.5 \ m \ Al_2(SO_4)_3$

Which among the following colligative properties is useful to determine molar masses of very expensive solutes?

Among the colligative properties,which one is the best method for the determination of the molar mass of proteins and polymers?

An aqueous solution has an osmotic pressure of $4.92 \text{ atm}$ at $300 \text{ K}$. Calculate the molarity of the solution. $(R = 0.082 \text{ L atm mol}^{-1} \text{ K}^{-1})$ (in $\text{ M}$)

The osmotic pressure of a solution is given by the relation
