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

Answer:

0.628 M.

  • Molarity = moles / liters

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

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