If the osmotic pressure of a solution at $300 \ K$ is $0.0821 \ atm$,what will be the concentration of the solution in $mol/L$?

Explain reverse osmosis and the purification of water.

The plot of osmotic pressure $(\Pi)$ vs concentration $\left(mol \ L^{-1}\right)$ for a solution gives a straight line with slope $25.73 \ L \ bar \ mol^{-1}$. The temperature at which the osmotic pressure measurement is done is
(Use $R=0.083 \ L \ bar \ mol^{-1} \ K^{-1}$) (in $^{\circ} C$)

At $27^{\circ}C$, $0.1 \ M$, $1 \ L$ $K_4[Fe(CN)_6]$ aqueous solution and $0.1 \ M$, $1 \ L$ $FeCl_3$ aqueous solution are placed in a container separated by a semi-permeable membrane $AB$. Assume complete dissociation of both the solutes. Which of the following statements is correct?

What is edema?

$\pi = \text{..........}$
