Question

Copper has a density of 10.5g/cm³ and gold has a density of 19.3g/cm³. Which would have a greater mass, 6 cm of copper or 3 cm of gold?

a) Copper

b) Gold

Answer 1

After calculating the mass of each sample using their respective densities, 6 cm³ of copper has a mass of 63 g, and 3 cm³ of gold has a mass of 57.9 g, hence copper has the greater mass.

Step-by-step explanation:

To determine which metal would have a greater mass, we need to calculate the mass of each sample separately. Copper has a density of 10.5 g/cm³, and gold has a density of 19.3 g/cm³. We can calculate their masses using the density formula mass = density × volume.

For 6 cm³ of copper, the mass would be:
10.5 g/cm³ × 6 cm³ = 63 g

For 3 cm³ of gold, the mass would be:
19.3 g/cm³ × 3 cm³ = 57.9 g

Comparing the two, copper has the greater mass.
