|The objects should separate according to their densities. |GASOLINE |
|Aluminum will sink to the bottom, since it is denser than any |wood |
|of the liquids. Ice will sink in the ethanol, but float above | |
|the water. Wood sinks in the gasoline, but floats above the |ETHANOL |
|ethanol. The order of densities is indicated below: |ice |
| | |
|aluminum > seawater > water > ice > ethanol > wood > gasoline |WATER |

2. The calculated density of the crown is 12.6 g/mL (56.7 g/4.5 mL), which rounds off to 13 g/mL. This value indicates that the crown CANNOT be made of pure gold, which has a density of 19.3 g/mL. The crown could be made of lead (density = 11.3 g/mL) and plated with a layer of gold. The resulting crown would be expected to have a density between that of lead and gold, but much closer to that of lead. A density value of 13 g/mL supports this hypothesis.
