yes

no

not enough information

9. Eggs sink when placed in water. If I dissolve enough salt in the water the egg begins to float. Why?

Salt stuck to the egg making it have more mass and thus less density.

Adding salt lowered the density of the egg causing it to float

More mass was added to the water making the water more dense than the egg.
