Ii Review | Constants Periodic Table When backpacking in the wilderness, hikers often boil water to sterilize it for drinking. Suppose that you are planning a backpacking trip and will need to boil 30 L of water for your Part A group What volume of fuel should you bring? Assume the following: the fuel has an average formula of C,H16; 15% of the heat generated from combustion goes to heating the water (the rest is lost to the surroundings); the density of the fuel is 0.78 g mL' and the density of water is 1.00 g mL 1; the initial temperature of the water is 25.0 °C; and the standard enthalpy of formation of C,H16 is -224.4 kJ mol 1, of CO2(g) is – 393.5 kJ mol 1, and of H2O(g) is –241.8 kJ mol 1. The heat capacity of water is 4.184 J/(g . °C). Express your answer in litres to two significant figures. • View Available Hint(s) ΥΠ ΑΣφ
