Density Lab Report Abstract For the indirect determination of density of a pre-1985 penny, Archimedes’ displacement principle was utilized. When pennies were placed in the cylinder containing water, the increase in liquid level accounted for the displaced amount of water or the amount necessary to evaluate the density of the penny given the mass of a couple of pennies for each of five recorded sets.…
