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 $R = 0.083 \ L \ bar \ mol^{-1} \ K^{-1}$)

$A$ solution of urea contains $8.6 \ g/L$ (mol. wt. $60.0$). It is isotonic with a $5\%$ solution of a non-volatile solute. The molecular weight of the solute will be:

At a certain temperature, the value of the slope of the plot of osmotic pressure $(\pi)$ against concentration $(C \text{ in } mol \ L^{-1})$ of a certain polymer solution is $291 \ R.$ The temperature at which osmotic pressure is measured is: $(R \text{ is the gas constant})$

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

The relationship between osmotic pressure at $273 \ K$ when $10 \ g$ glucose $(P_1)$,$10 \ g$ urea $(P_2)$,and $10 \ g$ sucrose $(P_3)$ are dissolved in $250 \ mL$ of water is:

Which of the following pairs of solutions is expected to be isotonic at the same temperature?
