Density of Metals Lab Use the following table to answer questions 3 & 4 Data and Observations Data Table Sample Mass (g) Volume of water (ml) Volume of water + sample (ml) Volume of sample (ml) Density (g/ml) 3. Find the density of a substance that has a volume of 754cm3 and a mass of 7917g. Using table 1 above identify the substance using the density you found. Post Lab 1. List the metals samples in order of increasing density. 2. What is the possible identity of each sample? If you are unable to positively identify a metal indicate that by writing “unable to identify.” A= ____________________ B= ____________________ C= ____________________ D=_____________________ E=_____________________ 4. A balloon contains helium with a mass of 0.00296014g. What is the volume of helium in the balloon (use table 1 above)? 5. Write 2 sentences about what you learned in this lab.
