The latent heat of vaporisation of water is $9700 \, Cal/mole$ and if the boiling point is $100 \, ^oC$,the ebullioscopic constant of water is .......... $^oC \, kg/mol$.

The vapour pressure vs. temperature curve for a solution-solvent system is shown below. The boiling point of the solvent is $........\,^{\circ} C$.

The solution containing $3 \ g$ urea (molar mass $60 \ g \ mol^{-1}$) per $dm^3$ of water and another solution containing $4.5 \ g$ of solute $A$ per $dm^3$ of water boil at the same temperature. What is the molar mass of $A$?

When a substance is dissolved in a solvent,the vapour pressure of the solvent decreases. It brings:

If $10 \ g$ of a solute (molar mass $= 100 \ g/mol$) is dissolved in $100 \ g$ of water,then the molal elevation constant $K_b$ of the solvent will be equal to:

The molal elevation constant is the ratio of the elevation in boiling point to the $......$.
