## How To Prepare 0.1 M Koh Solution

How would you make 120 mL of a 0.10 M solution of potassium hydroxide in water? Solution: The amount of KOH required is (0.120 L) × (0.10 mol L –1) = 0.012 mol. The molar mass of KOH is 56.1 g, so the weight of KOH required is (.012 mol) × (56.1 g mol –1) = 0.67 g. We would dissolve this weight of KOH in a volume of water that is less than 120 mL, and then add sufficient water to bring
