Quizplus · Accepted Answer

Molarity is defined as the number of moles of solute per liter of solution. Therefore, the one liter of 2.0 M KCl solution contains 2.0 moles of KCl, while the two liters of 1.0 M KCl solution contain 2.0 moles of KCl (1.0 M x 2 L = 2.0 moles). Therefore, they have the same number of moles of solute.
