Question

3. What amount of

space is taken up by a rock that weighs 150 milligrams, and
has a density of 30 mg/ml? (Express your answer in Liters)

Answer 1

Hey there!:

Density = 30 mg/mL

Mass = 150 mg

Volume = ??

Therefore:

D = m / V

30 = 150 / V

V = 150 / 30

V = 5.0 mL

converts volume into liters :

5.0 mL / 1000 => 0.005 L or 5.0 x 10⁻³ L

Hope this helps!
