Osmotic pressure of a solution containing $0.1 \ mol$ of solute per litre at $273 \ K$ is (in $atm$):

Pure water can be obtained from sea water by

$A$ $5.25\%$ solution of a substance is isotonic with a $1.5\%$ solution of urea (molar mass $= 60\ g\ mol^{-1}$) in the same solvent. If the densities of both the solutions are assumed to be equal to $1.0\ g\ cm^{-3},$ the molar mass of the substance will be .............. $g\ mol^{-1}$.

At a certain temperature,the osmotic pressure of a $0.25 \, M$ solution of a non-electrolyte is $\pi \, bar$. What will be the osmotic pressure of a $0.125 \, M \, Ba(NO_3)_2$ solution at the same temperature?

The value of osmotic pressure of a $0.2 \ M$ aqueous solution at $293 \ K$ is ........... $atm$.

The osmotic pressure of a sugar solution at $300 \ K$ is $2.46 \ atm$. What is the concentration of the solution (in $M$)?
