$A$ $5\%(w/v)$ solution of sucrose is isotonic with a $1\%(w/v)$ solution of substance '$A$'. What is the molar mass of substance '$A$'?

Determine the osmotic pressure of a solution prepared by dissolving $25 \, mg$ of $K_{2}SO_{4}$ in $2 \, L$ of water at $25^{\circ} C$,assuming that it is completely dissociated.

$A$ $1.17 \%$ solution of solute $A$ is isotonic with a $7.2 \%$ solution of glucose. If the molecular weight of solute $A$ is $58.5$, the value of the van't Hoff factor,'$i$',is:

Which particles can pass through a semipermeable membrane?

The solution in which the blood cells retain their normal form is with regard to the blood:

Which of the following pairs of aqueous solutions exhibits the same osmotic pressure at the same temperature? $\left[ \text{Molar mass of urea} = 60 \ g \ mol^{-1}, \text{sucrose} = 342 \ g \ mol^{-1} \right]$
