$3 \ mL$ of solution was made by dissolving $20 \ mg$ of protein at $0^{\circ} C$. The osmotic pressure of the resulting solution is $3.8 \ torr$. The molecular weight of the protein is approximately $(g/mol)$

If a thin slice of sugar beet is placed in a concentrated solution of $NaCl$,then...

If a $6.84 \% (wt./vol.)$ solution of cane sugar $(mol. wt. 342)$ is isotonic with a $1.52 \% (wt./vol.)$ solution of thiocarbamide,then the molecular weight of thiocarbamide is:

The osmotic pressure at $17 \ ^oC$ of an aqueous solution containing $1.75 \ g$ of sucrose per $150 \ mL$ solution is .......... $atm$.

$A$ solution of $12 \ g$ of non-electrolyte $(A)$ prepared by dissolving it in $1000 \ mL$ of water exerts the same osmotic pressure as that of a $0.05 \ M$ glucose solution at the same temperature. The empirical formula of $A$ is $CH_2O$. The molecular mass of $A$ is $.......... \ g \ mol^{-1}$. (Nearest integer)

$A$ $1\% \ (wt/vol) \ KCl$ solution is ionised to the extent of $80\%$. The osmotic pressure at $27 \ ^oC$ of the solution will be .......... $atm$.
