When 9.00 g of methane, CH₄(g), are burned in a bomb calorimeter with a heat capacity of 66.0 kJ/K, the temperature of the calorimeter assembly rises by 7.59 K. What is the standard enthalpy of combustion of methane? Assume ΔU_combustion ≈ ΔH_combustion.
a) –1252 kJ mol⁻¹
b) –31.3 kJ mol⁻¹
c) –281 kJ mol⁻¹
d) –501 kJ mol⁻¹
e) –891 kJ mol⁻¹
