Answer: The given statement is false.
Step-by-step explanation:
Total number of particles present in a substance determines the concentration of particles present.
It is known that in solids, molecules are held together due to strong intermolecular forces of attraction. As a result, solids have definite shape and volume.
So, more is the number of particles present in the solid phase more will be the concentration in solid phase.
Therefore, we can conclude that the statement, concentration of the particles in the solid phase always remains the same regardless of how much quantity is present, is false.
