An autonomous underwater vehicle (AUV) is designed to map the seabed of a marine sanctuary. The AUV's propulsion and sensor systems require an average of 3.5 kJ3.5\text{ kJ}3.5 kJ of energy to travel 1 m1\text{ m}1 m. The onboard fuel cell runs on a liquid chemical fuel that has an energy content of 1050 kJ/mol1050\text{ kJ/mol}1050 kJ/mol.
Calculate the number of moles of this fuel needed by the AUV to complete a mapping mission of length 4.8 km4.8\text{ km}4.8 km.
