For questions 3 – 9, calculate the density and fill in the table.
10. What has the greater density, a cube of water measuring 1cmX1cmX1cm and having a mass of
1g, or a block of plastic measuring 2cmX3cmX1cm with a mass of 4g?
A Cube of water
B Block of plastic
11. A rock has a volume 57 cm3. Its mass is
555.75 g. What is the density of this rock?
12. Joe has to find the density of a rectangular
box. He measures the width to be 6 cm, the
length to be 7 cm, and the height to be 2 cm.
He put the box on a balance and the mass is
198.24 g. What is the density of the box?
14. Sam has to find the density of an
irregularly shaped solid. The mass of the solid
is 300.3 g. She uses water displacement to find
the volume. The volume of the water alone is
100 mL. The volume of the water with the solid
in it is 142 mL. What is the density of the
solid?
15. Based on the table below, what is the
irregularly shaped solid in question 14 likely
made of?

13. We need to find the density of a cube of
plastic that has sides measuring 4 cm. The
mass of the cube is 279.744 g. What is the
density of the cube?

16. Mr. Odum wants to know if his watch band
is titanium or silver. He measures the mass of
his watch band to be 90 g. The volume of his
watch band is 20 cm3. Using the table above,
what is his watch band likely made of?

Use the table to help you answer questions 17 –21.
Metal
Average Density
Lithium
0.53 g/cm3
Beryllium
1.85 g/cm3
Gallium
5.91 g/cm3
Tin
7.26 g/cm3
Nickel
8.92 g/cm3
Palladium
12.0 g/cm3
Platinum
21.5 g/cm3
17. The mass of an unknown metal is 222.5 g.
Mrs. de Leon used water displacement to measure
the volume of the mineral. The picture below
shows the volume in mL before and after the metal
was added to the graduated cylinder. Find the
volume and then the density. Use the table above
to identify the metal.
19. Mr. Valamides brought his cuff links down to
6th grade Science to find out if they were really the
metal that he thought they were. We found the
mass to be 720.25 g. When we put the cuff links
into a graduated cylinder with 100 mL of water in
it, the water rose 33.5 mL. Mr. Valamides was very
happy with the result because he knew the metal
was ______________________________.
20. Mr. Odum was teaching Mrs. Burch how to find
the volume of an unknown metal using water
displacement. The picture below shows what Mrs.
Burch saw.
The metal is _____________________________
Mrs. Burch measured the mass of the metal and
the balance read 145.2 g. Mrs. Burch used the
table to identify the mineral as Gallium. Was she
correct? ____________
18. Mr. Odum measured the next metal and found
the volume was 27 mL and mass was 14.31 g.
Calculate density, then use the table above.
21. Ms. Blackmon brings in a metal that she thinks
is Palladium. She gives it to Mrs. de Leon so that
she can find out for sure. The mass of the metal is
163.8 g. The volume is 13.65 mL. Does Ms.
Blackmon have the metal that she thinks she has?
The metal is __________________________
