Due Date:
1. Write the Density formula below.
2. Calculate the density of the metal cube listed below. The mass is 8 grams and the
volume is 4 cm3. What is the density? Show your work using the IFSMU method.
3. Imagine that the cube is split in half exactly.
What is the mass of one half of the cube? ____________
What is the volume of one half of the cube?____________
Calculate the density. Show your work using the IFSMU method.
4. Based on your answers to #2 and #3, does size affect density? Explain your answer.
5. Circle the less dense item. (Refer to the density table on the back if needed)
a. wood or pure water
b. steel or pure water
c. helium or air
d. gasoline or water
6. What is the mass of 25 mL of water? Explain how you got your answer.
7. The mass of an unknown metal is 45 g and the volume is 4 cm3. Calculate the
metal’s density. Show your work using the IFSMU method.
8. Based on your answer to #7, what is the identity of the unknown metal?

9. Circle the materials that will float on water (density of water = 1 g/cm3)
corn oil = .93 g/cm3
glycerin = 1.26 g/cm3
corn syrup = 1.38 g/cm3
wood = .85 g/cm3
steel = 7.81 g/cm3
rubber = 1.34 g/cm3
ice = .92 g/cm3
10. Assuming the materials above don’t mix, show how the materials would "stack up" in
a graduated cylinder.
11. Two students are trying to determine the density of an unknown liquid. They
measure the mass of an empty graduated cylinder as 27.25 g. They then pour in 16.5
ml of liquid. The mass of the liquid and the graduated cylinder is now 50.35 g. Show
your work as you calculate the density of the liquid. (IFSMU)
12. Another student has to determine the density of a rock sample. They first determine
the mass to be 81.0 g. Next they place it into a graduated cylinder containing 15.0 ml
of water. The rock causes the water to rise to the 33.0 ml mark on the cylinder. Show
your work as you calculate the density of the rock. (IFSMU)
13. These five balloons escaped from the balloon seller in the park. Each one is filled
