Which of the following colligative properties is most suitable for determining the molar mass of polymers?

An aqueous solution of volume $300 \, cm^3$ contains $0.63 \, g$ of protein. The osmotic pressure of the solution at $300 \, K$ is $1.29 \, mbar$. The molar mass of the protein is $......... \, g \, mol^{-1}$. Given : $R = 0.083 \, L \, bar \, K^{-1} \, mol^{-1}$

$A$ solution has an osmotic pressure of $x \ kPa$ at $300 \ K$ having $1 \ mole$ of solute in $10.5 \ m^{3}$ of solution. If its osmotic pressure is reduced to $(\frac{1}{10})$th of its initial value,what is the new volume of solution (in $m^{3}$)?

Which of the following pairs of solutions is expected to be isotonic at the same temperature?

Find out the osmotic pressure of a $0.2 \, M$ solution of glucose at $300 \, K$. (in $, \text{atm}$)

Isotonic solutions are solutions having the same
