Problem- 1) Determine the %KHP in an unknown sample (mass = 645 mg) that required an average of 15.27 mL of 0.0988 M NaOH to reach the endpoint. Show calculations.

2) If you prepared a solution of KOH by weighing out 6.255 g of solid KOH that had a purity of 87.5% and then diluted this to a final volume of 1 L in a volumetric flask, what would be the %KHP in an unknown sample (mass = 0.601 g) if it required 21.36 mL of KOH titrant to reach the endpoint? Show calculations.
