What units do we use for density?

• g/cm

• g/mL

• cm³

• g/cm³

• g/lb

Why do objects sink or float in H₂O? 

• Because their densities are higher or lower than compared to water
• Because their densities are using gravity to pull down
• Because their densities are heavier or lighter
• Because their mass and volumes are equal
