3. Pure aluminum metal has a density of 2.70 g/cm3. If we add a solid aluminum cylinder to a graduated cylinder containing 19.2 mL of water, and the water level in the cylinder rises to 24.7 mL, what is the mass of the aluminum cylinder? (show your work for full credit) 4. Acetone, a common solvent, has a density of 0.79 g/mL at 20oC.
EXPERIMENT 3: Identification of a Substance by Physical Properties
The density of a liquid is usually reported in units of grams per milliliter (g/mL). The density of a solid is reported in units of grams per cubic centimeter (g/cm3). Because 1 mL is equivalent to 1 cm3, these units are interchangeable. The density of water is 1.00000 g/cm3 at 4°C and is slightly less at room temperature (0.9970 g/cm3 at 25°C).

In this experiment, I measured the volume of water and oil with a graduated cylinder. I also measured the mass of each. When I divided the mass by the volume, I got the density. The density of the oil (0.922 g/mL) was less than the density of the water (0.998 g/mL). I then put water in a beaker and poured oil into the water.

Example: What is the volume of a piece of gold ( = 19.3 g/cm3) that has a mass of 12.4 g? Solution: We can use the density to convert between the mass and the volume. 𝑐 I3 33 Note: Since both the density and the mass are measured to 3 significant digits, the answer should be rounded to three significant digits as well.
