Lab Skills

Density If a sample of aluminum has a mass of 13.5 g and a volume of 5.0 cm 3, what is its density? Insert the known quantities for mass and volume into the density equation. Density is a property that can be used to identify an unknown sample of matter. Every sample of pure aluminum has the same density.
