Which of the following colligative properties can provide the molar mass of proteins,polymers,and colloids with greater precision?

The molar mass of a solute $X$ in $g \ mol^{-1}$, if its $1 \%$ solution is isotonic with a $5 \%$ solution of cane sugar (molar mass $= 342 \ g \ mol^{-1}$), is

Which of the following aqueous solutions are isotonic $(R = 0.082 \ atm \ K^{-1} mol^{-1})$?

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.

Calculate the molar mass of a non-electrolyte solute when $6 \text{ g}$ of it is dissolved in $1 \text{ dm}^3$ of water, having an osmotic pressure of $2.4 \text{ atm}$ at $300 \text{ K}$ $(R = 0.0821 \text{ atm dm}^3 \text{ K}^{-1} \text{ mol}^{-1})$.

At $310 \ K$,the osmotic pressure of blood is $7.65 \ atm$. An aqueous solution of glucose will be isotonic with blood at a concentration of ........ $\%$ (weight/volume).
