Pumice is volcanic rock that contains many trapped air bubbles. A sample displaced 236.6 mL inside a graduated cylinder filled with water. Assume a pumice rock density of 0.95g/cm^3. What is the mass of the pumice rock?

Density = Mass / Volume
Mass of the pumice rock
= Volume × Density
= (236.6 mL) × (0.95 g/cm³)
= (236.6 cm³) × (0.95 g/cm³)
= 225 g
Mass of the pumice rock
= Volume × Density
= (236.6 mL) × (0.95 g/cm³)
= (236.6 cm³) × (0.95 g/cm³)
= 225 g
