What is the molarity of a solution that contains 0.220 moles KOH in 0.350 L of solution?


  1. Answer:

    0.628 M.


    In order to solve this problem we need to keep in mind the definition of molarity:

    • Molarity = moles / liters

    We are given both the number of moles and the volume of solution, meaning we can now proceed to calculate the molarity:

    • Molarity = 0.220 mol / 0.350 L
    • Molarity = 0.628 M
