Calculation of Molar Internal Energy of Combustion in a Bomb Calorimeter

Given:

  • Mass of compound A = 0.5 g

  • Molar mass of compound A = 50 g/mol

  • Temperature rise in the bomb calorimeter = 4 K

  • Heat capacity of the calorimeter and material = 2.5 kJ/K



Formula:

  • Molar internal energy of combustion = (Heat released / Number of moles of compound A)



Calculation:

  • Number of moles of compound A = (Mass of compound A / Molar mass of compound A) = (0.5 g / 50 g/mol) = 0.01 mol

  • Heat released = (Heat capacity of the calorimeter and material) x (Temperature rise in the bomb calorimeter) = (2.5 kJ/K) x (4 K) = 10 kJ

  • Molar internal energy of combustion = (Heat released / Number of moles of compound A) = (10 kJ / 0.01 mol) = 1000 kJ/mol



Conclusion:

  • The molar internal energy of combustion of compound A in a bomb calorimeter is 1000 kJ/mol.
