What mass of solute (molar mass $58 \ g \ mol^{-1}$) is to be dissolved in $2.5 \ dm^3$ $H_2O$ to generate osmotic pressure of $0.245 \ atm$ at $300 \ K$ (in $g$)? $(R = 0.0821 \ dm^3 \ atm \ K^{-1} \ mol^{-1})$.

Which of the following is an excellent semipermeable membrane?

The osmotic pressure of a solution at $327\,^oC$ and concentration $C$ is $P$. If the osmotic pressure of the same solution at concentration $C/2$ and temperature $427\,^oC$ is $2\, atm$,then the value of $P$ is:

$0.05 \ M \ CuSO_4$ when treated with $0.01 \ M \ K_2Cr_2O_7$ gives a green coloured solution of $Cu_2Cr_2O_7$. In an osmosis setup with a Semi Permeable Membrane $(SPM)$ separating Side $X$ $(K_2Cr_2O_7)$ and Side $Y$ $(CuSO_4)$,determine the observation due to osmosis.

The empirical formula of a non-electrolyte is $CH_{2}O$. $A$ solution containing $6 \ g$ of the compound exerts the same osmotic pressure as that of $0.05 \ M$ glucose solution at the same temperature. The molecular formula of the compound is

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