4. The density of copper is 8.9 g/cm. Its relative density is​

Answer 1

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. 8.9 × 1000 = 8900 kg/m^

Answer 2

Answer:

$\huge\mathfrak\purple{☆Answer☆}$

Explanation:

Relative density =>Density of substance/Density of water at 4°C.

Density of Copper =>8.9g/cm.

Density of water=> 1000g/cm.

So relative desity=> 8.9/1000

=>8.9/10*10*10

=>8.9/10^3

=>8.9*10^-3.

So the relative density of copper is 8.9*10^-3 (0.0089).
