A.) You are givena cube of silver metal that measures 1.000cm on each edge. The density of silver is 10.5 g/cm^3. How many atoms are in this cube?
B.) Because atoms are spherical, they cannot occupy all of the space of the cube. The silver atoms pack in the solid in a such a way that 74% of the volume of the solid is actually filled iwth the silver atoms. Calculate the volume of a sphere, calculate the radius in angstroms fo a silver atom.
