Scuba divers carry ballast weights to have neutral buoyancy. At that condition, the buoyancy force on the diver exactly balances weight, and there is no tendency either to float toward the surface or to sink. In freshwater, a certain diver carries 10 lb of lead alloy ballast of density 1.1 x 104 kg/m3. During an excursion in seawater, the diver must carry 50% more ballast to remain neutrally buoyant. How much does this diver weigh
