Objective: The objective of this lab is to receive two unknown pieces of metal and determine the identity of each. This was to be done by calculating the densities of each in two ways, then compare it to the density chart. By doing this, one should be able to determine which metal each unknown specimen was. Materials: 1) 2 unknown metals 2) 25ml graduated cylinder 3) Analytical balance Method: 1) Obtain 2 unknown metals from the instructor. 2) Weigh the unknown metals individually on the balance and record the mass of each. 3) Measure and record the diameter and length of each unknown metal. 4) Calculate the volume of both metals, using the new data. 5) For each metal, use the 25ml graduated cylinder to measure the volume of the 2 metals, using water displacement. 6) Record the measured water before and after you put the metal into the cylinder. Data: Unknown 1 Unknown 2 Mass of specimen 28.8g 17.5 Dimensions of specimen (Length) 3.2cm 5.0cm Dimensions of specimen (Diameter) 1.2cm 1.2cm
