Explanation / Answer

Density = mass/volume or D = m/v. Each substance has its own characteristic density because of the size, mass, and arrangement of its atoms or molecules.

A submerged object displaces a volume of liquid equal to the volume of the object.

Here

Mass = 3.40 g

Volume = 12.96 ml -12.25 ml = 0.71 ml

Density = Mass / Volume = 3.40 g / 0.71 ml = 4.788 g/ml = 4.79 g/ml
