If $3 \ g$ of glucose (mol. wt. $180$) is dissolved in $60 \ g$ of water at $15 \ ^oC$. Then the osmotic pressure of this solution will be .......... $atm$.

Calculate the amount of solute dissolved in $3 \ dm^3$ water having osmotic pressure $0.3 \ atm$ at $300 \ K$. (Molar mass of solute $= 108 \ g \ mol^{-1}, R = 0.0821 \ atm \ dm^3 \ K^{-1} \ mol^{-1}$) (in $g$)

What will be the osmotic pressure of a $0.03 \ N$ solution of Aluminium sulphate at $27 \ ^\circ C$? If the salt dissociation in the solution is $90 \ \%$,the osmotic pressure is . . . . . . $atm$.

At the same temperature,which of the following pairs of solutions will be isotonic?

Which of the following pairs of solutions is isotonic?
