Asolid object has a density of 2.85 g/cm3. according to archimedes, what can be done to make this object float in water?

nothing can make this object float because it is too dense.
cut the object down to one third of its current size.
reshape the object so that it displaces more than its own weight of water. decrease the density of the object by making its volume smaller.

Both josef loschmidt and amedeo avogadro contributed to our understanding of basic molecular numbers, sizes, and reaction ratios. neither scientist discovered “avogadro’s number” in the form we use it today (6.02 x 10 23). still, there’s a controversy over the name. research the contributions from these two scientists and read about how avogadro’s number got its name. briefly state what you think this number should be called, providing key details of each scientist’s contributions to this concept and a solid rationale for your case in naming the number.
