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