Answer: measure the volume of water poured into a graduated cylinder ,then place the object in the water and remeasure the volume.The difference between the two volume measurements is the volume of the objects .Now simply divide the mass by the volume
to calculate the density of the object.
Or The mass and size of molecules in a liquid and how closely they are packed together determine the density of the liquid. Just like a solid,the density of a liquid equals the mass of the liquid divided by its volume; D =m/v.The density of the water is one gram per cubic centimeter.
