Lets see: you want to dilute it by 2.73/1.68 or 1.625 times.
Which means, you need one part KOH, and .625 parts diluting water.
So what is one part? Easy: 153.2 is one part, and then water of 153.2*.625 ml water. Stir, label, and store properly.
How many milliliters of water must be added to 153.2 mL of 2.73 M KOH to give a 1.68 M solution?
