(D) The molar mass of $NH_4NO_3$ is $80 \ g/mol$. The heat released during the decomposition of $1 \ g$ of $NH_4NO_3$ is given by $q = C \times \Delta T$. $q = 1.23 \ kJ/K \times 6.12 \ K = 7.5276 \ kJ$. Since the decomposition is exothermic,the enthalpy change for $1 \ g$ is $-7.5276 \ kJ$. The molar enthalpy of decomposition is calculated as $\Delta H = -7.5276 \ kJ/g \times 80 \ g/mol = -602.208 \ kJ/mol$. Therefore,the value is approximately $-602 \ kJ/mol$.
