(D) The molar mass of chlorine $(Cl)$ is $35.5 \ g \ mol^{-1}$.Number of moles of $Cl = \frac{1 \ g}{35.5 \ g \ mol^{-1}} = \frac{1}{35.5} \ mol$.The energy released for $1 \ mol$ of $Cl$ is $3.7 \ eV \times 23.06 \ kcal \ mol^{-1} \ eV^{-1} = 85.322 \ kcal \ mol^{-1}$.Energy released for $\frac{1}{35.5} \ mol = \frac{1}{35.5} \times 85.322 \ kcal \approx 2.4 \ kcal$.
