The Thickness of Aluminum Foil Lab In the study of Chemistry‚ we encounter very large and very small numbers. For example‚ the size of a molecule or thin layer of molecules is very‚ very small and difficult to measure directly. In order to “measure” such numbers‚ we often use one measured quantity and another known property to calculate the unknown value. In this experiment‚ we will use this approach to calculate the thickness of various types of aluminum foil‚ a quantity whose direct experimental
