Q. The mass of a copper atom is 2.38 x 10-25 kg, and the density of copper is 8 920 kg/m3.
(a) Conclude the number of atoms in 1 cm3 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 out the edge dimension of each cube that represents an estimate for the spacing between atoms.
