What does NOT change when a solution is diluted by the addition of solvent?
- volume of solvent. IT CHANGES. The new volume will be the sum of the previous volume of the solvent and the added one.
- mass of solvent. IT CHANGES. The new mass will be the sum of the previous mass of the solvent and the added one.
- number of moles of solute. IT DOES NOT CHANGE. The number of moles of solute are not modified.
- molarity of solution. IT CHANGES. The molarity is the number of moles of solute divided by the liters of solution. As the volume of the solution increases due to the addition of solvent, the molarity of the solution will decrease.
