A metal ball has a mass of 2kg and a volume of 6 ml What is its density?

Answer 1

density = mass / volume

→ density_ball = 2kg / 6ml = 1/3 kg/ml ≈ 0.333 kg/ml

If you want it in other units:

1 ml = 1 cm³

→ density ≈ 0.333 kg/cm³

1 kg = 1000 g

→ density ≈ 333 g/cm³

1 m³ = 1000000 cm³

→ density ≈ 333,333 kg/m³

That is one dense material of which the ball has been made (Mercury has a density of 13,594 kg/m³, so the material is about 25 times denser than mercury) - have you got your units correct?

Answer 2

0.333kg/ml
