Question

A piece of copper of mass is 8.9 kg has a volume 0.001 m³. What is the density of copper?

Answer 1

Answer:

Density of copper d = 8.9 g cm-3

= 8.9 × 1000 kg m -3

[∵ 1 g cm-3 = 1000 kg m-3]

= 8900 kg m‐³

Answer 2

Given :-

• A piece of copper of mass is 8.9 kg has a volume 0.001 m³.

To find :-

• Density of copper

Solution :-

• Mass of copper = 8.9 kg

• Volume of copper = 0.001m³

As we know

→ D = M/V

Where " D " is density, " M " is mass and " V " is volume.

• According to the given condition

→ Density = 8.9/0.001

→ Density = 89/1 × 1000/10

→ Density = 89 × 100

→ Density = 8900kgm¯³

Hence,

• Density of copper is 8900kgm¯³
