The osmotic pressure of a dilute solution is given by

If a solution has an osmotic pressure of $0.82 \ bar$ at $27 \ ^oC$,find the concentration of such a solution. (in $M$)

$A$ semipermeable membrane is that which permits the passage of:

To have an osmotic pressure equal to a solution containing $9.2 \ g$ of glucose per liter,how many grams of glucose must be dissolved in $0.5 \ L$ of solution?

$A$ $1.17 \%$ solution of solute $A$ is isotonic with a $7.2 \%$ solution of glucose. If the molecular weight of solute $A$ is $58.5$, the value of the van't Hoff factor,'$i$',is:

The osmotic pressure exerted by a solution prepared by dissolving $2.0 \ g$ of protein of molar mass $60 \ kg \ mol^{-1}$ in $200 \ mL$ of water at $27^{\circ} C$ is $.....Pa$. [integer value]
(use $R = 0.083 \ L \ bar \ mol^{-1} \ K^{-1}$)
