Answer 2

The density of copper in kg/m³ is 8960 kg/m³.

Given:

The volume of copper =  1x10⁻⁵ m³

Mass of copper = 89.6 g

To Find:

The density of copper in kg/m³.

Solution:

We are required to find the value of the density of copper in kg/m³.

We know density is given as

Density, d = mass(m)/ volume(v)  -----(1)

Mass of the copper, m = 89.6 g

m =  89.6×10⁻³ kg

Volume, v = 1x10⁻⁵ m³

On substituting the values of m and v in equation(1) we get

Density, d = 89.6×10⁻³/ 1x10-5

d = 89.6 × 10² kg/m³

d = 8960 kg/m³

Therefore, The density of copper in kg/m³ is 8960 kg/m³.
