What is the osmotic pressure $(\pi)$ of a $0.02 \ M$ solution of $NaCl$ (in $RT$)?

Which of the following $0.1 \ M$ solutions has the maximum osmotic pressure at $25^o \ C$?

Identify the correct statement regarding $0.2 \text{ M}$ urea and $0.2 \text{ M}$ sucrose solutions.

At $298 \, K$,the ratio of osmotic pressures of two solutions of a substance with concentrations of $0.01 \, M$ and $0.001 \, M$ respectively,is

$A$ solution containing $4 \ g$ of polymer in $4.0 \ L$ solution at $27^{\circ} C$ shows an osmotic pressure of $3.0 \times 10^{-4} \ atm$. The molar mass of the polymer in $g \ mol^{-1}$ is

$A$ solution containing $4 \ g$ of a non-volatile organic solute per $100 \ mL$ has an osmotic pressure of $500 \ cm$ of mercury at $27^\circ C$. What is the molar mass of the solute?
