Question

The density of copper is 8.9g/cm³. Calculate relative density

Answer 1

Answer:

hello dear,

Explanation:

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^3.

Answer 2

• Density if copper=8.9g/cm^3=0.89kg/m^3
• Density of water at 4°C=1000kg/m^3

We know

$\boxed{\sf Relative\:Density=\dfrac{Density\:of\:substance}{Density\:of\:water\;at\:4°C}}$

$\\ \sf\longmapsto Relative\:Density=\dfrac{0.89}{1000}$

$\\ \sf\longmapsto Relative\:Density=890$
