What is the density of lithium metal (in g/cm3) if a cube measuring 0.82 cm x 0.95 cm x 2.548 mm has a mass of 0.572 g?

I'm still stuck on this can I please get help


Sagot :

Density is mass per unit volume. A cube with dimensions 0.82 cm by 0.95 cm by 2.548 mm has a volume of

(0.82 cm) × (0.95 cm) × (0.2548 cm) ≈ 0.1985 cm³

Then the density of this cube, given that it has a mass of 0.572 g, is approximately

(0.572 g) / (0.1985 cm³) ≈ 2.88 g/cm³
