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

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

The osmotic pressure of a living cell is $12 \ atm$ at $300 \ K$. The strength of sodium chloride solution that is isotonic with the living cell at this temperature is $...... \ g \ L^{-1}$. (Nearest integer)
Given : $R = 0.08 \ L \ atm \ K^{-1} \ mol^{-1}$
Assume complete dissociation of $NaCl$
(Given : Molar mass of $Na$ and $Cl$ are $23$ and $35.5 \ g \ mol^{-1}$ respectively.)

The pressure required for the reverse osmosis is quite high. For this,which of the following membranes is used?

Solution $A$ contains $7 \ g/L$ of $MgCl_2$ and solution $B$ contains $7 \ g/L$ of $NaCl$. Which of the following is true regarding their osmotic pressure at room temperature?

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.
