The elevation in boiling point of a solution containing $1.8 \ g$ of glucose in $100 \ g$ of solvent is $0.1^{\circ}C$. The value of $K_b$ for the solvent is ........ $\frac{K}{m}$.

$0.1 \ molal$ aqueous solution of glucose boils at $100.16^{\circ} C$. What is the boiling point of a $0.5 \ molal$ aqueous solution of glucose (in $^{\circ} C$)?

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 $100^{\circ} \, C$?

$13.44 \ g$ of $CuCl_2$ is dissolved in $1 \ kg$ of water. Determine the elevation in boiling point of the solution. [$K_b = 0.52 \ K \ kg \ mol^{-1}$,$mol \ wt$ of $CuCl_2 = 134.4$]

$A$ solution of a non-volatile solute has a boiling point elevation of $0.70 \text{ K}$. If $K_b$ for the solvent is $2.44 \text{ K kg mol}^{-1}$, what is the molality of the solution (in $\text{ m}$)?

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 $(K_b = 2.16 \ K \ kg \ mol^{-1})$.
