The osmotic pressure of a dilute solution is $7 \times 10^5 \ Pa$ at $273 \ K$. Osmotic pressure of the same solution at $283 \ K$ is . . . . . . . $\times 10^4 \ Nm^{-2}$.

The osmotic pressure of which solution is maximum? (Consider that a $0.1 \ M$ solution of each is $90\%$ dissociated.)

$200 \, cm^3$ of an aqueous solution of a protein contains $1.26 \, g$ of the protein. The osmotic pressure of such a solution at $300 \, K$ is found to be $2.57 \times 10^{-3} \, bar$. Calculate the molar mass of the protein.

Which one of the following is an isotonic pair of solutions?
