The process in which solvent molecules pass through a semipermeable membrane is called:

Discuss the biological and industrial importance of osmosis.

Which of the following solutions has the highest osmotic pressure?

$A$ $1\% \ (wt/vol) \ KCl$ solution is ionised to the extent of $80\%$. The osmotic pressure at $27 \ ^oC$ of the solution will be .......... $atm$.

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 polystyrene in benzene contains $10 \, g/L$. The equilibrium height of the column of solution having density $0.9 \, g/mL$ in the osmometer is $11 \, cm$ at $27 \, ^\circ C$. What is the average molar mass of polystyrene? (Assume the solution is ideal)
