The elevation in boiling point for one molal solution of a solute in a solvent is called

The boiling point of a solution of $0.11 \ g$ of a substance in $15 \ g$ of ether was found to be $0.1 \ ^\circ C$ higher than that of the pure ether. The molecular weight of the substance will be $(K_b = 2.16 \ K \ kg \ mol^{-1})$.

Which of the following aqueous solutions will exhibit the highest boiling point?

Boiling point of water at $750 \, mm \, Hg$ is $99.63^{\circ} \, C$. How much sucrose is to be added to $500 \, g$ of water such that it boils at $100^{\circ} \, C$?

Molal elevation constant is the elevation in boiling point produced by

If $0.15 \ g$ of a solute dissolved in $15 \ g$ of solvent is boiled at a temperature higher by $0.216 \ ^oC$ than that of the pure solvent,what is the molecular weight of the substance? (Given: molal elevation constant for the solvent is $2.16 \ ^oC \ kg \ mol^{-1}$)
