Given:
- Mass of NH4NO3 = 1 gram
- Temperature increase in the calorimeter = 6.12 K
- Heat capacity of the system = 1.23 KJ/g-1 - deg-1

To find:
- Molar heat of decomposition for NH4NO3

Concept:
The heat capacity of a system is defined as the amount of heat required to raise the temperature of the system by 1 degree Celsius or 1 Kelvin.

The molar heat of decomposition can be calculated using the equation:
Molar heat of decomposition = (Heat capacity of the system * Mass of NH4NO3 * Temperature increase) / Molar mass of NH4NO3

Calculation:
1. Calculate the molar mass of NH4NO3:
NH4NO3 = (1 * 14.01) + (4 * 1.01) + 14.01 + (3 * 16.00)
= 80.04 g/mol

2. Substitute the given values into the equation:
Molar heat of decomposition = (1.23 KJ/g-1 - deg-1 * 1 g * 6.12 K) / 80.04 g/mol

3. Simplify the expression:
Molar heat of decomposition = (1.23 KJ * 6.12 K) / 80.04 g/mol
= 7.53 KJ/mol

Answer:
Therefore, the molar heat of decomposition for NH4NO3 is -7.53 KJ/mol, which is option (D).
