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

At $0^{\circ} C$,a urea solution has an osmotic pressure of $400 \ mm$. On dilution by $x$ times,its osmotic pressure decreases to $100 \ mm$ at $20^{\circ} C$. The dilution factor $x$ is approximately

Osmotic pressure of the solution can be increased by,

Find out the osmotic pressure of a $12 \% \ w/V$ $KCl$ solution at $27 \ ^oC$. (in $atm$)

$A$ solution of a nonvolatile solute is obtained by dissolving $0.8 \ g$ in $0.3 \ dm^3$ of water. The solution has an osmotic pressure of $0.2 \ atm$ at $300 \ K$. Calculate the molar mass of the solute. $[R = 0.082 \ atm \ dm^3 \ K^{-1} \ mol^{-1}]$

Arrange the following equimolar solutions according to increasing order of osmotic pressure [Assume complete ionisation]:
$A$. $KCl$
$B$. $BaCl_2$
$C$. $AlCl_3$
$D$. $Al_2(SO_4)_3$
