The values of observed and calculated molecular weights of silver nitrate are $92.64$ and $170$ respectively. The degree of dissociation of silver nitrate is:

The vapour pressure of pure liquid $\mathrm{A}$ is $10 \mathrm{torr}$ and at the same temperature when $1 \mathrm{g}$ of $\mathrm{B}$ solid is dissolved in $20 \mathrm{g}$ of $\mathrm{A}$, its vapour pressure is reduced to $9.0 \mathrm{torr}$. If the molecular mass of $\mathrm{A}$ is $200 \mathrm{amu}$, then the molecular mass of $\mathrm{B}$ is:

The vapour pressure of a solution of a non-volatile solute $\mathrm{B}$ in a solvent $\mathrm{A}$ is $95\%$ of the vapour pressure of the solvent at the same temperature. If the molecular weight of the solvent is $0.3$ times the molecular weight of the solute, what is the ratio of weight of solvent to solute?

Osmotic pressure of solution of glucose is $1.20 \mathrm{atm}$ and that of solution of cane sugar is $2.5 \mathrm{atm}$. The osmotic pressure of the mixture containing equal volumes of the two solutions will be:

A solution of a substance containing $1.05 \mathrm{g}$ per $100 \mathrm{mL}$ was found to be isotonic with $3\%$ glucose solution. The molecular mass of the substance is:

What is the effect of the addition of sugar on the boiling and freezing points of water?

Which of the following shows negative deviation from Raoult's law?

The azeotropic mixture of water $\left(\mathrm{b}.\mathrm{p}.100°\mathrm{C}\right)$ and $\mathrm{HCl}\left(\mathrm{b}.\mathrm{p}.85°\mathrm{C}\right)$ boils at $108.5°\mathrm{C}$. When this mixture is distilled it is possible to obtain?
