How much heat (in kJ) is required to warm 12.0 g of ice, initially at -11.0 °C to steam at 112.0 °C? The heat capacities of ice, water, and steam are 2.09, 4.18, and 2.01 J·g⁻¹·°C⁻¹ respectively. The enthalpy of fusion of ice is 6020 J·mol⁻¹ and the enthalpy of vaporization of water is 40,700 J·mol⁻¹. Express your answer in kilojoules to three significant figures.
The heat of combustion of CH4 is 890.4 kJ/mol and the heat capacity of H2O is 75.2 J/mol × K.
