Richard L. Keiter and Whitney L. Puzey , Erin A. BlitzJournal of Chemical Education2006 83 (11), 1629Metal rods of high purity for many elements are now commercially available and may be used to construct a display of relative densities. We have constructed a display with nine metal rods (Mg, Al, Ti, V, Fe, Cu, Ag, Pb, and W) of equal mass whose ...
