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

What is the osmotic pressure (in $atm$) of $0.02 \ M$ aqueous glucose solution at $300 \ K$?
$(R=0.082 \ L \ atm \ mol^{-1} \ K^{-1})$

The osmotic pressure in atmospheres of a $10\%$ solution of cane sugar at $69\,^oC$ is:

Calculate the osmotic pressure of $0.03 \ mol$ of non-electrolyte solute dissolved in $0.1 \ dm^3$ of water at $300 \ K \ [R=0.0821 \ dm^3 \ atm \ mol^{-1} \ K^{-1}]$ (in $atm$)

If a $6.84 \% (wt./vol.)$ solution of cane sugar $(mol. wt. 342)$ is isotonic with a $1.52 \% (wt./vol.)$ solution of thiocarbamide,then the molecular weight of thiocarbamide is:

Which of the following is $NOT$ used as a semipermeable membrane?
