2a. Density is the relationship between mass and volume. Density has
many uses but is most commonly used to help determine the identity of
an unknown substance. Specifically for copper the proportion is
approximately 8.96 grams for every mL of copper. Approximately how
much volume (mL) would 29 grams of copper have? While it is helpful for
you to show all work, you MUST provide rationale for your thinking and
explanation for each of your steps.

The volume of copper : 3.24 ml

Further explanation

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:

[tex]\large{\boxed {\bold {\rho~=~ \frac {m} {V}}}}[/tex]

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 :

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