Density is a relationship between Mass and Volume. Mass / Volume = Density
Density = Mass / Volume
50g = 50 ML 1g/ML or 9.CM3

The denser an object is the Heavier it is.
A. The density of water is 1g/cm3 anything a density greater it sink's in water.
B. Anything with a density smaller it will float in water.
A substace's density is unqiue and constant unless the tempature changes.
Heat decreases density because substances expand ( greater volume, Less mass)
Cold increases density because substances contract ( less volume, More Mass)
So why does water expand when it freezes? Crystal structure takes up more space than free moving molecules. Ice is the exception.
Ice float's there fore it is less dense than water.
If an item breaks doe's it change? No
