Standardization of a sodium hydroxide (NAOH) solution against potassium hydrogen phthalate (KHP) yielded the following results: Mass of KHP, g 0.7987 Volume of NaOH, mL 38.29 0.8365 38.96 0.8104 38.51 38.29 0.8039 MM KHP: 204.22 MM NaOH: 40.00 a. Calculate the mean molar concentration of sodium hydroxide. (First, compute the concentration of NaOH in each titration then compute for its mean/average value.) b. Calculate the standard deviation. Please provide solutions for your answers. If you have used your calculator for calculating for mean and standard deviation, you can just provide the formula with the values indicated.
