why is density a useful way to identify a substance?

Brief Explanations:
Density is a characteristic property. Each substance has a unique density under specific conditions. It relates mass and volume, and measuring it helps in identification as no two pure substances have exactly the same density at the same temperature and pressure.
Answer:
Density is a characteristic property of a substance, and different substances have distinct densities under specific conditions, allowing for identification.
