Density is useful for identifying an unknown material because it is a physical constant. A physical constant is a unique characteristic of the material in question. This constant never change or vary with the shape or amount of the material/substance.

It is one factor amongst many which will help.
The physical properties of a pure substance can be used to identify it. A pure substance is an element or a compound, not a mixture.

Because size and weight can vary.
Density is specific for each substance. Also the measurement is generally simple.
Color and streak would be the least useful, because they may be shared by a multitude of other minerals.
