The boiling points of two miscible liquids, which do not form an azeotropic mixture, are close to each other. Their separation is best carried out by:

By dissolving $0.35$ $\mathrm{mole}$ of sodium chloride in water, $1.30 \mathrm{L}$ of salt solution is obtained. The molarity of the resulting solution should be reported as:

Upon mixing equal volumes of aqueous solutions of $0.1 \mathrm{M} \mathrm{HCl}$ and $0.2 \mathrm{M} {\mathrm{H}}_2{\mathrm{SO}}_4,$ the concentration of ${\mathrm{H}}^{+}$ in the resulting solution is:

The percentage of nitrogen by mass in ammonium sulphate is the closest to $($atomic masses $\mathrm{H}=1, \mathrm{N}=14, \mathrm{O}=16, \mathrm{S}=32)$

Complete reaction of $2.0 \mathrm{g}$ of calcium (atomic weight $=40$) with excess $\mathrm{HCl}$ produces $1.125 \mathrm{L}$ of ${\mathrm{H}}_2$ gas. Complete reaction of the same quantity of another metal ${}^{"}\mathrm{M}^{"}$ with excess $\mathrm{HCl}$ produces $1.85 \mathrm{L}$ of ${\mathrm{H}}_2$ gas under identical conditions. The equivalent weight of ${}^{"}\mathrm{M}^{"}$ is closest to:

The plot of total vapour pressure as a function of mole fraction of the components of an ideal solution formed by mixing liquids $\mathrm{X}$ and $\mathrm{Y}$ is:

The boiling point of $0.001 \mathrm{M}$ aqueous solution of $\mathrm{NaCl}, {\mathrm{Na}}_2{\mathrm{SO}}_4, {\mathrm{K}}_3{\mathrm{PO}}_4$ and ${\mathrm{CH}}_3\mathrm{COOH}$ should follow the order:

At $298 \mathrm{K}$, the ratio of osmotic pressures of two solutions of a substance with concentrations of $0.01 \mathrm{M}$ and $0.001 \mathrm{M}$, respectively, is:
