Question

what determines how much, if any, of a solute is dissolved?
application
equality
saturation
salinity

Explanation:

Saturation refers to the point at which a solvent can no longer dissolve any more solute under given conditions. It determines the maximum amount of solute that can be dissolved. Application and equality are not relevant factors here. Salinity is a measure related to salt - content in a solution, not the general determinant of solute dissolution amount.

Answer:

C. saturation
