As a result of osmosis,the volume of the solution...

Which of the following solutions has the highest osmotic pressure?

Which particles can pass through a semipermeable membrane?

$A$ 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)

$0.05 \ M \ CuSO_4$ when treated with $0.01 \ M \ K_2Cr_2O_7$ gives a green coloured solution of $Cu_2Cr_2O_7$. In an osmosis setup with a Semi Permeable Membrane $(SPM)$ separating Side $X$ $(K_2Cr_2O_7)$ and Side $Y$ $(CuSO_4)$,determine the observation due to osmosis.

Calculate the osmotic pressure of a solution containing $0.025 \ mol$ of glucose in $100 \ mL$ of water at $300 \ K$. $\left[R = 0.082 \ atm \ dm^3 \ mol^{-1} \ K^{-1}\right]$ (in $atm$)
