Calculate the osmotic pressure of a $0.1 \ M$ aqueous solution of an electrolyte at $300 \ K$ if the van't Hoff factor is $1.125$. $[R = 0.0821 \ atm \ dm^3 \ K^{-1} \ mol^{-1}]$ (in $atm$)

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: $(R \text{ is the gas constant})$

If $3 \ g$ of glucose (molar mass $= 180 \ g \ mol^{-1}$) is dissolved in $60 \ g$ of water at $15^{\circ} C$,the osmotic pressure of the solution will be (in $atm$)

What does a semi-permeable membrane allow to pass through?

The osmotic pressure at $17 \ ^oC$ of an aqueous solution containing $1.75 \ g$ of sucrose per $150 \ mL$ solution is .......... $atm$.

Which of the following pairs of solutions are expected to be isotonic,temperature being the same?
