Calculate the enthalpy of vaporisation per mole for ethanol. Given `DeltaS = 109.8 J K^(-1) mol^(-1)` and boiling point of ethanol is `78.5^(@)`.

Explanation

To calculate the enthalpy of vaporization per mole for ethanol, we can use the relationship between enthalpy change (ΔH) and entropy change (ΔS) at the boiling point. The formula we will use is:

\[ \Delta H = T \times \Delta S \]

where:
- \( \Delta H \) is the enthalpy of vaporization,
