Verified Answer
The density of copper is 9 g/cm3. Then the volume of 90 g copper is...
Density of copper = 9 gm/cm^3
Mass of copper = 90 g
We know; Density = mass / volume
⇒ volume = mass / density
⇒ 90 / 9
⇒ Volume = 10 cm3
Mass of copper = 90 g
We know; Density = mass / volume
⇒ volume = mass / density
⇒ 90 / 9
⇒ Volume = 10 cm3

The density of copper is 9 g/cm3. Then the volume of 90 g copper is...
Calculation of Volume of Copper
Given, density of copper = 9 g/cm3 and mass of copper = 90 g
We know that,
Density = Mass/Volume
Volume = Mass/Density
Substituting the given values in the above equation, we get
Volume = 90/9
Volume = 10 cm3
Therefore, the volume of 90 g copper is 10 cm3.
Explanation
Density is defined as the amount of mass present per unit volume of a substance. It is denoted by the symbol 'ρ'. The SI unit of density is kg/m3 or g/cm3.
In the given problem, we are given the density of copper and the mass of copper. We are required to find the volume of copper.
Using the formula for density, we can find the volume of copper. We substitute the given values of mass and density in the formula and calculate the volume.
The volume of copper comes out to be 10 cm3. This means that if we take a piece of copper with a mass of 90 g, its volume will be 10 cm3.
Therefore, the correct option is D) 10 cm3.
