A geologist wants to determine the density of obsidian using a sample of small, irregular obsidian chips.
The geologist has access to:
Describe an experimental procedure the geologist should follow to determine, as accurately as possible, the density of the obsidian. Your description should include how the geologist can minimise experimental errors in both the mass and volume measurements.
