The mass of a copper atom is 1.06E-25 kg, and the density of copper is 8920 kg/m.3. (a) Determine the number of atoms in 1 cm.3 of copper. (b) Visualize the one cubic centimeter as formed by stacking up identical cubes, with one copper atom at the center of each. Determine the volume of each cube. (c) Find the edge dimension of each cube, which represents an estimate for the spacing between atoms.
