1. Prior to placing a 5.158 g piece of metal into the graduated cylinder, the level was 5.0 mL. After adding the metal, the observed level was 5.1 mL.  Does this result appear reasonable?  Explain

What experimental factors could have caused this result?

2. Why might it be difficult to use this exact experimental setup to measure the density of a 29.010 g piece of Al (d= 2.70 g/mL).  A calculation is required.

3. Draw a single test tube containing the following three substances, 10.0 g of water, 10.0 g of ice and a 10.0 g sphere of lead. Label each substance in the test tube. Properly depict the relative volumes.
