2. Direct titration: 10.25 ± 0.02 mL of an unknown KHP solution required 11.60 ± 0.02 mL of 0.1110 ± 0.0006 M NaOH to reach the end point. a. What is the concentration of KHP in the unknown solution reported with uncertainty? + M b. If the unknown solution was prepared by dissolving 5.128 g of the unknown KHP (204.22 g/mol) in 100.00 mL of water, what is the weight percent of KHP in the sample? KHP %w/w
