Answer:
Density is the total number of particles in a given volume
Explanation:
As per the particle theory, density is defined as total space occupied by certain number of particles of any given element with in a defined volume is termed as density.
Density is not the denseness of a single unit but the space occupied by many single units with in a given volume V
Hence, density is the total number of particles in a given volume.
Carbon: 12.01
Neon: 20.18
Iron:55.85
Uranium: 238.03
