Answer:
copper
Explanation:
The density of copper is 8.96 g/cm³ and the density of zinc is 7.13 g/cm³.
density= mass/volume
⇒mass = density×volume
For copper,
mass = 8.96 g/cm³ × 1 cm³
mass = 8.96 grams
For zinc,
mass = 7.13 g/cm³ × 1 cm³
mass = 7.13 grams
It is clear that, the mass of copper is more.
