Because when salt is dissolved in a solvent its particles occupy empty space between molecules of the solvent hence the volume remains constant.

Answer:
volume of a solution does not change because we know that particles of matter have space between them and when we dissolve salt the space get occupied by particles of salt.
Explanation:
When you add table salt (sodium chloride, NaCl) to water, the salt dissolves into ions, Na+ and Cl-. The volume increases by a small factor, but the mass increases by a bigger factor.
