The osmotic pressure of $1 \, M$ solution at $27 \, ^\circ C$ is ........... $atm$.

If the osmotic pressure of a solution at $300 \ K$ is $0.0821 \ atm$,what will be the concentration of the solution in $mol/L$?

If $A$ contains $2\% \ NaCl$ and it is separated by a semipermeable membrane from $B$ which contains $10\% \ NaCl$,which event will occur?

Which of the following is $NOT$ used as a semipermeable membrane?

$x \% (w/v)$ solution of urea is isotonic with $4 \% (w/v)$ solution of a non-volatile solute of molar mass $120 \ g \ mol^{-1}$. The value of $x$ is

$A$ $0.002 \, M$ solution of $NaCl$ having a degree of dissociation of $90 \%$ at $27 \, ^{\circ}C$ has an osmotic pressure equal to:
