2. Using the density principle... Conclusions: The average density of the metal in part A was 89. The metal was identified to be Copper. The average data had a percent error of %. The solution in part B had an average density of 2.727 gml. Correct
Purpose: The purpose of this lab is to determine the density of a metal cylinder and a solution different methods to determine volume. The calculated density was then used to identify the metal in the cylinder. Procedure: The procedure was followed as described in the FSCJ lab manual. Data: A. Cylinder Number/letter (if there was one) N/A Appearance of Cylinder copper Mass (g) length (cm) B ^56.43 Volume from Dimensions (mL) 6.63 B.
