2a. Density is the relationship between mass and volume. Density has

Charra [1.4K]

The volume of copper : 3.24 ml

<h3>Further explanation </h3>

Density is a quantity derived from the mass and volume

Density is the ratio of mass per unit volume

With the same mass, the volume of objects that have a high density will be smaller than objects with a smaller type of mass

The unit of density can be expressed in g/cm³ or kg/m³

Density formula:

$\large{\boxed {\bold {\rho~=~ \frac {m} {V}}}}$

ρ = density , g/cm³ or kg/m³

m = mass , g or kg

v = volume , cm³ or m³

A common example is the water density of 1 gr / cm³

The density of copper : 8.96 gr/ml

mass of copper : 29 g

then the volume :

$\tt V=\dfrac{m}{\rho}\\\\V=\dfrac{29~g}{8.96~g/ml}\\\\V=\boxed{\bold{3.24~ml~or~3.24~cm^3}}$
