A sample of a liquid which has molar mass $102\frac{g}{m}ol$ was placed in an electrically heated vessel. When the pressure was $650$ Torr the liquid boiled at $78C.$ After the boiling point had been reached, it was found that a current of $0\mathrm{.}232$A from a $12\mathrm{.}0V$ supply passed for $650s$ vaporized $1\mathrm{.}871g$ of the sample. Calculate the molar enthalpy and internal energy of vaporization.

$H_{\text{v}\text{a}\text{p}}=98\mathrm{.}7\frac{kJ}{m}ol,U_{\text{v}\text{a}\text{p}}=95\mathrm{.}8\frac{kJ}{m}ol$
