We’re asked to determine the **final ****volume **of a 1.5 M KOH solution prepared from an initial 5M KOH solution of 0.2 L.

Since we’re adding water to a concentrated solution of KOH and diluting it, we need the dilution equation:

What volume (L) of a 1.5 M KOH solution can be prepared by diluting 0.2 L of a 5M KOH solution? Show your work.
