1.1. A student finds a small rock that she suspects is a meteorite. 

Measuring the density of the rock will give one piece of evidence to support her idea.

State the equation that links density (ρ), mass (m) and volume (v).

1.2. Describe how the student could measure the volume of the piece of rock.

1.3. The volume of the piece of rock was 120.0 cm³.

The student measured the mass of the piece of rock as 895 g.

Calculate the density of the rock in g / cm³.

1.4. The graph in Figure 5 below shows the densities of some common types of rock.

Figure 5

Which type of rock most closely matches the rock the student measured?

1.5. Give one error that the student could have made when measuring the volume of the rock.

1.6. What effect would the error you described in part 4(e) have on the value of the volume of the rock that the student measured?
