Question

the relative density of copper is 8.9 what do you mean by this statement​

Answer 1

Answer:

Explanation:By definition, the specific gravity (or relative density) of a material is a ratio of the density of that material to the density of water at  

4  degree celsius.

which is the temperature at which water has its maximum density.

So if copper has a relative density of 8.9, it means that at  

4

, copper is 8.9 times more dense than water.

Answer 2

Answer:

HOPE THIS HELPS YOU...........

Explanation:

By definition, the specific gravity (or relative density) of a material is a ratio of the density of that material to the density of water at  4 ∘ C

which is the temperature at which water has its maximum density.

Ie.  S G s = ρ r e l = ρ s ρ H 2 O a t 4 ∘ C.

So if copper has a relative density of 8.9, it means that at  4 ∘ C

, copper is 8.9 times more dense than water.
