What will be the osmotic pressure of $0.2 \ M$ $K_4[Fe(CN)_6]$ at $27^{\circ} C$ (in $atm$)?

At the same temperature,which of the following pairs of solutions will be isotonic?

When two solutions $X$ and $Y$ are separated by a semi-permeable membrane and the solvent flows from $Y$ to $X$,then:

$x \% (w/v)$ solution of urea is isotonic with $4 \% (w/v)$ solution of a non-volatile solute of molar mass $120 \ g \ mol^{-1}$. The value of $x$ is

Which of the following statements is correct for an aqueous solution of $6 \ g \ L^{-1}$ urea and $17.12 \ g \ L^{-1}$ sucrose? [Molar mass of urea $= 60 \ g \ mol^{-1}$,Molar mass of sucrose $= 342 \ g \ mol^{-1}$]

Equal volumes of $0.2 \ M$ urea and $0.2 \ M$ glucose are mixed. The mixture will have
