the variables being changed between the two solutions. Which identification of the
variables is correct?
The volume of the solution and the number of solute particles are being
changed between the two solutions, but the concentration of the solution is
being held constant.
The volume of the solution and the concentration of the solution are being
changed between the two solutions, but the number of solute particles is being
held constant.
