When backpacking in wilderness, hickers often boil water to sterilize it for drinking. Suppose that you are planning a backpack trip and will need to boil 35 L of water for your group, how many L of fuel should you bring? Formula for fuel C7H16. 15% of heat generated from combustion goes to heat the water. Density of fuel is 0.78 g/mL. Initial temp is 25 degree Celsius and standard enthalpy of C7H16 is -224.4 kJ/mol.
