SHOW YOUR CALCULATIONS CLEARLY. THE MOLAR MASS OF KHP = 204.22 g/mol The following data represent the average from two best runs. Average Mass KHP (g) 0.7621 Initial Buret Reading (mL) 0.00 Final Buret Reading (mL) 14.95 Volume of NaOH used ____________ Average Molarity of NaOH ____________ Part B: Determination of the molarity of an Unknown Acid. The standard solution form Part A is used to determine the molarity of an unknown acid. A 15.00 mL sample of Unknown acid is titrated with the standard base where V i = 0.25 mL and V f = 30.15 mL, what is the concentration of the unknown acid if its structure is? 1. HA 2. H 2 A 3. H 3 A...
