Question

The density of a copper is 8.9 g\cm³ what will be its 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
