A 0.1326 g sample of magnesium was burned in an oxygen bomb calorimeter. The total heat capacity of the calorimeter plus water was 5,760 J/°C. If the temperature rise of the calorimeter with water was 0.570°C, calculate the enthalpy of combustion of magnesium.
Mg(s) + 1/2O2(g) → MgO(s)
(A) –3280 kJ/mol
(B) –24.8 kJ/mol
(C) 435 kJ/mol
(D) 106 kJ/mol
(E) –602 kJ/mol
