A block of ice has the density of 0.97 g/cm3. How much of it will sink below the surface of the water? (Points : 1)
About 97 percent of the ice will sink below water.
About 3 percent of the ice will sink below water.
All—100 percent—of the ice will sink below water.
None—0 percent—of the ice will sink below the water.

Ok I have no clue but I think its either the first, second, or last answer. I don't think it can be 100 percent
The 0.97 number for the density is wrong. It is actually 0.917.
97% would be the answer if the ice density were correct, but it isn't. The buoyancy force will equal the weight. This applies to pure water.
In ocean salt water, a smaller fraction is below water (about 88%). That is why icebergs float as high as they do in the water.
