If the mass of a spinel crystal is 9.5 grams what is the volume of this spinel crystal

Answer is: the volume of this spinel crystal is 2.5 cm³.

m (spinel crystal) = 9.5 g; mass of the crystal.

d (spinel crystal) = 3.8 g/cm³; density of the crystal.

V (spinel crystal) = m (spinel crystal) : d (spinel crystal).

V (spinel crystal) = 9.5 g : 3.8 g/cm³.

V (spinel crystal) = 2.5 cm³; volume of the crystal.
