Given parameters:

Mass of rock = 14g

Volume of rock = 12cm³

Unknown:

Density of the rock = ?

Density of a substance is the amount of substance it contains per unit volume. Mathematically, this can be expressed as;

           Density  = [tex]\frac{Mass}{Volume}[/tex]

Now simply input the parameters and solve;

         Density  = [tex]\frac{14}{12}[/tex]   = 1.17g/cm³

Density of the rock that Jack has is 1.17g/cm³
