calculate the minimum mass (in grams) of propane, C3H3(g), that must be combusted to provide the energy necessary to convert 3.80 kg of ice at -15.0 °C to liquid water at 80.0 °C. The enthalpy of fusion of ice is 6.02 kJ/mol, and the heat capacities for H₂O(l) and H₂O(s) are 4.184 J/g °C and 2.03 J/g. °C, respectively. (Assume the combustion of propane yields the H₂O product as a gas.)
