Purpose: The purpose of this lab is to determine the density of a metal cylinder and a solution, using 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) ^56.43 Volume from Dimensions (mL) B Volume from Displacement (mL) diameter (cm) mass before adding solution mass after adding solution Solution mass Solution volume (mL) Density of unknown solution с 1.3 density from dimensions 50 density from displacement 6.63 6 8.S 9.41 B. Unknown solution letter (if there was one) lemon juice Volume Before (mL) D Trial 2 Trial 3 Sample Calculations: Show on an attached sheet. 1) Volume from displacement 2) Volume from dimensions 3) Density from displacement 1) Doncity from dimensions Volume After (mL) E 56 average density 8.96 Trial 1 F27.319 Same as Trial 1 628.689 128.679 *28.6719 1.37 g 1.369 1.369 H2mL ¹2mL L 2mL 2.74gml 2,720 2.720g/ml Average density of unknown: 2,7279
3. Now that you have identified the metal, which method, displacement or dimensional, provided the most accurate answer? Explain, showing appropriate calculation/reasoning. accurate The meal is copps meshed for Cald Calcul
