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
