• Arnie has a low density because he is filled with air.

• Arnie's density is the same as water.

• Arnie's density cannot be determined without knowing his volume.

If Arnie the Doughnut were to be used in a science experiment to demonstrate osmosis, which of the following setups would be appropriate?

• Place Arnie in a sugar solution and observe if he shrinks.

• Place Arnie in a salt solution and observe if he expands.

• Place Arnie in pure water and observe if he absorbs water.
