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