Learn vocabulary, terms, and more with flashcards, games, and other study tools. 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 the volume of the solution up to 120 mL. For reference, a standard solution was prepared from 10.0 mg of NH 4 Cl (molar mass = 53.49 grams/mole) dissolved in 1.00 L of water. Then 10.0 mL of this standard was placed in a 50-mL volumetric flask, treated in the same manner as the unknown, and the absorbance found to be 0.323.
