2.2e Metal Identification by density Limitations and Applicability In part I of the expeniment, an unknown metal will be identffed through a determination of its density (d) in general, density alone would not be sufficient to identify a meal because the densty of some common metal like cobalt (Co. d=8.90gmL ), nickel (NL, d=8.91ginL ), and copper (Cu, d=8.96gmL ) are nealy identical. However, if the unknown metal is imited to the ten metals isted in Table 221, as is the case for part 1 of the experiment, a density determination is sufficient to identify the metal: Question 2.2.12 Enter the density values in gimL to the nearest 0.001gmL Include the unit using the symbol gimL. As an example, suppose a student determines the density of a motal samplo to be 1.695mL. with an estimated unceatainy of 25%. Ths means mhat the true deasity of the motal is between 95%of1.695gmL= and 105% of 1.6950mL= Usa the density range and the data in Table 2.2110 iconty the matat Name
