What is the molarity of ${\mathrm{H}}_{\mathrm{2}}{\mathrm{SO}}_{\mathrm{4}}$ solution, that has a density of $1.84 \mathrm{g}/{\mathrm{cm}}^3$ at $35°\mathrm{C}$ and contains solute $98\%$ by weight ?
 

The osmotic pressure of equimolar solutions of ${\mathrm{BaCl}}_2,\mathrm{NaCl}$ and glucose will be in the order

The mole fraction of ${\mathrm{C}}_3{\mathrm{H}}_5{\left(\mathrm{OH}\right)}_3$ in a solution of $36 \mathrm{g}$ of water and $46 \mathrm{g}$ of glycerine is:

A sample of air is saturated with benzene(vapour pressure $=100 \mathrm{mm} \mathrm{of} \mathrm{Hg}$ at $298 \mathrm{K}$) at $298 \mathrm{K}, 750 \mathrm{mm} \mathrm{of} \mathrm{Hg}$ pressure. If it is isothermally compressed to one third of its initial volume, the final pressure of the system is

Mixture of the volatile components $\mathrm{A}$ and $\mathrm{B}$ has the total vapour pressure (in $\mathrm{Torr}$) $\mathrm{p}=254-119{\mathrm{x}}_{\mathrm{A}}$ where ${\mathrm{x}}_{\mathrm{A}}$ is the mole fraction of $\mathrm{A}$ in the mixture. Hence ${\mathrm{p}}_{\mathrm{A}}^{°}$ and ${\mathrm{p}}_{\mathrm{B}}^{°}$ are: (in $\mathrm{Torr}$)

If '$\mathrm{A}$' contains $2\%\mathrm{NaCl}$ and is separated by a semi-permeable membrane from '$\mathrm{B}$' which contains $10\%\mathrm{NaCl}$, which event will occur?

Which of the following is not correct for an ideal solution?

If vapour pressures of pure liquids '$\mathrm{A}$' and '$\mathrm{B}$' are $300$ and $800 \mathrm{torr}$ respectively at $25°\mathrm{C}$. When these two liquids are mixed at this temperature to form a solution in which mole percentage of '$\mathrm{B}$' is $92$, then the total vapour pressure is observed to be $0.95 \mathrm{atm}$. Which of the following is true for this solution?
