  3. Row 1, Col 1 5 g/cm3 What is the density of a substance that has a mass of 125 g and a volume of 25 cm3?

  4. 1,2 mass When you graph data on the mass and volume of a substance, which variable goes on the y-axis?

  5. 1,3 Less, because water is less dense than lead. A cylinder of water that is equal in volume to a cylinder of lead will have more, the same, or less mass than the lead?

  6. 1,4 Measure the length, width and height and multiply them together. How would you find the volume of a large block of wood?

  7. 2,1 30 g What is the mass of 30 mL of water?

  8. 2,2 Since the mass divided by the volume for all amounts of the substance is the same, the points fall in a line. How does a graph of mass vs. volume tell you that density is a characteristic property?

  9. 2,3 B, because it has more matter in the same amount of space. Which is more dense and why? or A B

  10. 2,4 Water displacement What method would you use to determine the volume of a rock?

  11. 3,1 2.0 g/cm3 x 5 cm3 = 10 g An object with a density of 2.0 g/cm3 displaces 5 mL of water. What is its mass?

  12. 3,2 The line for water would be above the line for vegetable oil b/c water is more dense. On a graph of mass vs. volume, where would the line for water be compared with the line for vegetable oil?

  13. 3,3 They have the same density. Although B has more volume, it also has more matter. Also, the particles are spaced the same for both A and B. Which is more dense and why?

  14. 3,4 cm3 What units are used for the volume of an irregular solid?

  15. 4,1 The mass of the copper is 10 times greater than the mass of the wax. A piece of wax (0.9 g/cm3) and a piece of copper (9.0 g/cm3) have the same volume. How do their masses compare? Be specific!

  16. 4,2 Sink Consider a graph of m vs. V. Substances with lines that are steeper than the line for water would _____ when placed in water.

  17. 4,3 The cube of gold. (Size doesn’t matter) A cube of gold (19.3 g/cm3) and a cube of nylon (1.2 g/cm3) both have sides that are 2 cm in length. Which is more dense?

  18. 4,4 g/cm3 What units are used for the density of most substances that we measure in class?

  19. 5,1 24 g  1.2 g/cm3 = 20 cm3 A large nylon bolt has a density of 1.2 g/cm3 and mass of 24 g. What is it’s volume?

  20. 5,2 The data fell into two distinct lines that had different slopes (different densities) When graphing mass and volume data for the Density and Sample Size Lab, how could you determine that the cylinders were made from different substances?

  21. 5,3 B, because it has more matter particles. Which substance has a greater mass?

  22. 5,4 The substance will float in substances with a higher density and sink in substances with a lower density. How can a density column help you determine the density of a substance?
