The boiling point elevation of a solvent is observed to be \(2.3 \mathrm{~K}\) when \(13.86 \mathrm{~g}\) of a solute is added to \(100 \mathrm{~g}\). Calculate molal elevation constant \(K_{\mathrm{b}}\) and molar latent heat of vaporization \(L_{\mathrm{v}}\) of the solvent. Given that Molar mass of solvent \(=78 \mathrm{~g} / \mathrm{mol}\)

Boiling point \(=353.1 \mathrm{~K}\)

Molar mass of solute \(=154 \mathrm{~g} / \mathrm{mol}\).
