Osmotic pressure of a solution can be measured quickly and accurately by

Which of the following will have the minimum osmotic pressure?

$18 \ g$ glucose (Molar mass $= 180 \ g/mol$) is dissolved in $100 \ mL$ of water at $300 \ K$. If $R = 0.0821 \ L \ atm \ K^{-1} \ mol^{-1}$,what is the osmotic pressure of the solution (in $atm$)?

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 $atm$)

Diffusion of solvent through a semipermeable membrane is called

In case of osmosis,solvent molecules move from:
