Question

The density of Copper is 8.9g/cm3. What will be it's density in kg/m3 ?​

Answer 1

Answer:

Relative density is the density of a substance with respect to pure water at 4°C.

The density is water at 4° C is 1 g/cm^3.

As the relative density of copper is 8.9, it means that it's density is

8.9 g/cm^3

It can be converted to kg/m^3

1 g/cm^3 =

0.001 kg/ (0.000001 m^3)

So, 1 g/cm^3 = 1000 kg/m^3

Thus, density is copper is

8.9 × 1000 = 8900 kg/m^3.

Thus, density of copper is

8.9 g/cm^3 , or 8900 kg/m3

Answer 2

Answer:

8900 kg/m^3

Explanation:

thus 1 g cm^3 = 1000 kg m^3

therefore the density of copper is

= 8.9 × 1000

= 8900 kg/m^3
