The amount of a substance in a given volume.
Revise: Diffusion and factors affecting its rateIf a substance is more concentrated in one region than another, its particles gradually spread out. This process is diffusion: the spreading out of particles of a substance in solution, or particles of a gas, resulting in a net movement from an area of higher concentration to an area of lower concentration.
- Revise: Concentration of Solutions
