Example 2: Assuming that 1mL of potassium permanganate stock solution provides 1mg/L dosage in a 2L jar, what is the weight of potassium permanganate required to prepare 100mL of stock solution? Assume 100% purity. Example 1: Given that liquid alum is used as a coagulant. Specific gravity of alum is 1.33. One gallon of alum weighs 11.09 pounds (5.03kg) and contains 5.34 pounds (5.42kg) of dry alum. Determine: (a) the alum concentration, (b) mL of liquid alum required to prepare a 100mL solution of 20,000mg/L alum concentration, (c) the dosage concentration of 1mL of stock solution in a 2000ml Gator jar sample. solution
