While backpacking in the wilderness backpackers often boil water to sterilize it for drinking. Assume you are planning and need to boil 30 L of water for your group. Explain what volume of the fuel should you bring? Presume the following the fuel has an average formula of C7H16; 15% of the heat generated from combustion goes to heat the water (the rest is lost to the surroundings), the density of the fuel is .78g/ml, the initial temperature of the water is 25 degrees C; the standard enthalpy of formation of C7H16 is -224.24kJ/mole.
