What is true about the dissolving process in water

water molecules move throughout the solute is true.

step-by-step explanation:

that is true because it's about the dissolving process that is when solute is dissolved into solution. the water molecules moves throughout the solution. the solute molecules gets properly dissolved to form solution and gets uniformly distributed throughout the solution. it usually forms a homogeneous mixture in the solution.

$25

step-by-step explanation:

25 - 4.50 = 20.5
