You are given a cube of silver metal that measures1.012 cm on each edge. The density of silver is 10.5 g/cm3. The cube is composed of6.08x1022 silver atoms. Because atoms are spherical, they cannot occupy all of the space of the cube. The silver atoms pack in the solid in such a way that 74% of the volume of the solid is actually filled with the silver atoms. Calculate the volume of a single silver atom with the correct number of significant figures. Then, using the volume of a silver atom and the formula for the volume of a sphere, calculate the radius in angstroms of a silver atom (again, using the correct number ofsignificant figures).
