A sample of methylhydrazine (rocket fuel) weighing 1.500 g was ignited in a bomb calorimeter initially at 25.0°C, producing a temperature rise of 10.215 K. Determine the internal energy (∆U) of combustion of methylhydrazine. To properly determine the internal energy of combustion methylhydrazine, the calorimeter was first calibrated. A 0.6500 g sample of sucrose (MW 342.296 g/mol)) was ignited under identical conditions and produced a temperature rise of 1.98 K. For sucrose, the internal energy combustion at constant volume, ∆U, is known to be –5616.64 kJ/mol. Calculate the calorimeter constant, in kJ/K.
