Explanation:
Density is defined as mass per unit volume.
Mathematically, [tex]d = \frac{m}{V}[/tex]
where, d = density
m = mass
V = volume
It is given that volume is [tex]5.74 cm^{3}[/tex] and mass is 28.7 g. Then calculate the density as follows.
[tex]d = \frac{m}{V}[/tex]
= [tex]\frac{28.7 g}{5.74 cm^{3}}[/tex]
= [tex]5 g/cm^{3}[/tex]
Therefore, we can conclude that the density of that mineral fragment is [tex]5 g/cm^{3}[/tex].
