1. **State the problem:** We need to find how much more the weight of the Huygens lander is on Earth compared to Titan, expressed in kilograms. 2. **Given data:** - Weight on Earth = 700 lbs - Weight on Titan = 43.76 kg 3. **Convert weight on Earth from pounds to kilograms:** - Use the conversion factor: $1 \text{ lb} = 0.453592 \text{ kg}$ - Calculate weight on Earth in kg: $$700 \times 0.453592 = 317.5144 \text{ kg}$$ 4. **Calculate the difference in weight:** - Difference = Weight on Earth (kg) $-$ Weight on Titan (kg) - $$317.5144 - 43.76 = 273.7544 \text{ kg}$$ 5. **Round the answer to the nearest hundredth:** - $$273.75 \text{ kg}$$ **Final answer:** The Huygens lander weighs 273.75 kg more on Earth than on Titan.
