Relative decrease in vapour pressure is $0.4$ for a solution containing $1\mathrm{ }\mathrm{m}\mathrm{o}\mathrm{l}\mathrm{e}\mathrm{ }\mathrm{A}\mathrm{B}$ in $3\mathrm{ }\mathrm{m}\mathrm{o}\mathrm{l}\mathrm{ }{\mathrm{H}}_2\mathrm{O}$, therefore $\mathrm{A}\mathrm{B}$ is ionised at the extent of

If the osmotic pressure of a 0.010 M aqueous solution of sucrose at ${27}^{\text{o}}\text{C}$ is 0.25 atm, then the osmotic pressure of a 0.010 M aqueous solution of NaCl at ${27}^{\text{o}}\text{C}$ is

The value of observed and calculated molecular weight of calcium nitrate are $65$ and $164$. The degree of dissociation of $\mathrm{Ca}{\left({\mathrm{NO}}_3\right)}_2$ will be:-

The partial dissociation appears to be a major factor in determining the properties of weak electrolytes and the degree of dissociation for weak electrolyte at dilution v is given by $\text{α}=\frac{{\text{Λ}}_{\text{v}}}{{\text{Λ}}_{\infty }}$. The strong electrolytes on the other hand do not obey this relation and the variation of molar conductivity for strong electrolytes is given by ${\text{Λ}}_{\text{v}}={\text{Λ}}_{\infty }-{\text{bc}}^{1/2}$.

The graph plotted for log ($\text{i-1}$)vs. log ${\text{Λ}}_{\text{v}}$, where i is van't Hoff factor for uni-univalent electrolyte and ${\text{Λ}}_{\text{v}}$, is its molar conductivity at concentration c does not show the following characteristics:

Assume 100% ionisation of $\mathrm{N}\mathrm{a}\mathrm{C}\mathrm{l}$ and $\mathrm{C}\mathrm{a}\mathrm{C}{\mathrm{l}}_2$ in the solvent and molality = molarity
