If ${\chi }_1$ and ${\chi }_2$ represent the mole fractions of a component $A$ ' in the vapour phase and liquid mixture respectively, and $p_A°$ and $p_B°$ represent vapour pressures of pure $A$ and pure $B$, then total vapour pressure of liquid mixture is

The solubility of pure oxygen in water at $20°\mathrm{C}$ and $1.0$ atmosphere pressure is $1.38\times {10}^{-3}$ mol/litre. What will be the concentration of oxygen at $2\theta °\mathrm{C}$ and partial pressure of $0.21$ atmosphere?

Benzene freezes at $5.6°\mathrm{C}$. Its ${\mathrm{K}}_{\mathrm{f}}$ value is $5.1$. The value of $\Delta {\mathrm{H}}_{\text{fus }}$ is:

$0.02$ molar solution of $\mathrm{NaCl}$ having degree of dissociation of $90\%$  at $27°\mathrm{C}$ has osmotic pressure equal to

Water $+{\mathrm{CH}}_3\mathrm{OH}$ mixture shows positive deviation from ideal solution behaviour $100 \mathrm{mL}$ of water is mixed with $100 \mathrm{mL}$  of ${\mathrm{CH}}_3\mathrm{OH}$. Then, total volume of the mixture will be
