1. a computer disk drive is composed of many layers. The primary layer is made of aluminum and is 1.0 mm thick. If the diameter of an aluminum atom is 2.5 angstroms, how many aluminum atoms thick is the primary layer?
2. If the diameter of the aluminum nucleus was 4 x 10^‐¹⁵m (to the negative 15), how much of the 1.0 mm thickness is actually occupied by the nuclei of the Al atoms?
3. Explain what occupies the remaining space in the thickness of the computer disk primary layer.
