For a material to float on the surface of water, the material must have a density
less than that of water (1.0 g/ml) and must not react with the water or dissolve in
it. A spherical ball has a radius of 0.50 cm and weighs 2.0 g. Will this ball float or
sink when placed in water? (Note: Volume of a sphere = 4/3(pi)(r^3)
