```Density of an Unknown Substance
Table 1 .Density
of Liquids
Use the information provided on the Table to identify three unknown
substances by calculating their densities. Remember, density equal
mass divided by volume.

5. If you were to pour these substances into one graduated cylinder, describe how they
would be arranged in the graduated cylinder.
6. Utilize the information in Table 1 to color the
graduated cylinder diagram with the appropriate
volume of each liquid. Label the name of each Liquid.
7. What two physical properties must you know before
you can calculate the density of a substance?
8. What instruments could you use in lab to measure
those properties of a liquid?
