4.3.1.1 Required practical 5 — Density

What you do (method)

• Measure mass using a balance.
• Measure volume:
  • regular solid: use ruler → calculate volume
  • irregular solid: displacement can / measuring cylinder
• Calculate density: ρ = m / V.

Common mistakes

• Mixing units (cm³ vs m³; g vs kg).
• Reading meniscus wrong in measuring cylinder.
