Question

Quizplus · Accepted Answer

Molarity (M) is defined as the number of moles of solute per liter of solution.

Molarity = moles of solute / liters of solution

In this case, we are given that the solution contains 5.0 moles of KCl in 2.0 L.

Molarity = 5.0 moles / 2.0 L = 2.5 M

Therefore, the molarity of the solution is 2.5 M. The correct answer is D.
