Icebergs consist of freshwater ice and float in the ocean with only about 9.60% of their volume above water (the "tip of the iceberg," so to speak). This percentage can vary, depending on the condition of the ice. Assume that the ice has the density 0.92×103kg/m3, although, in reality, this can vary considerably, depending on the condition of the ice and the amount of impurities in it.
What does this 9.60% tell us is the density of seawater?
What percentage of the icebergs' volume would be above water if they were floating in a large freshwater lake such as Lake Superior?

If an object floats in a liquid then the density of the solid is less than that of the liquid.

Ice bergs are basically made of fresh water.  So an iceberg in freshwater will have what?
neutral buoyancy.

perl · Answer

there might be a formula

anonymous · Answer

neutral buoyancy means that it is totally submerged but does not sink.  It stays at the depth that it is placed.
