Question

the density of copper is 8.4 g/cm cube . what will be the volume of 200 g of copper

Answer 1

Heya,

Given,

Density = 8.4 g/cm^3

Mass = 200g

Density = mass/volume

Volume = mass/ density

= 200/8.4

= 2000/84

=23.80 cm^3

Hope it helps U...

Answer 2

Concept:

A density of a substance or material is defined as its mass per unit volume.

Given:

The density of copper is $8.4g/cm^3$ and the given mass of copper is $200g$.

Find:

The volume of copper.

Solution:

The density of copper, $\rho =8.4g/cm^3$.

Mass of copper, $m=200g$.

The formula for density is given as:

$\rho =\frac{m}{V}$ , where $m,V$ are the mass and volume respectively.

So,

$\rho =\frac{m}{V}$

$8.4g/cm^3=\frac{200g}{V}$

$V=\frac{200g}{8.4g/cm^3}$

$V=23.809cm^3$

The volume of $200g$ of copper is $23.809cm^3$.
