You have two HCl solutions, labeled solution A and solution B. Solution A has a greater concentration than solution B. Which of the following statements is/are true?
A) If you have equal volumes of both solutions, solution B must contain more moles of HCl.
B) If you have equal moles of HCl in both solutions, solution B must have a greater volume.
C) To obtain equal concentrations of both solutions, you must add a certain amount of water to solution B.
D) Adding more moles of HCl to both solutions will make them less concentrated.
E) At least two of the above statements are true.

B) If you have equal moles of HCl in both solutions, solution B must have a greater volume. This is because concentration is defined as the amount of solute (in this case, HCl) per unit volume. If solution A is more concentrated than solution B, then for both solutions to have the same number of moles of HCl, solution B must have a larger volume to accommodate the same amount of HCl at a lower concentration.
