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 38L of water for your group.What volume of fuel should you bring? Assume each of 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 0.78 g/mL the initial temperature of the water is 25.0 degrees C and the standard enthalpy of formation of C7H16 is -224.4 kJ/mol. Answer in mL.
