Standardization of a sodium hydroxide solution against potassium hydrogen phthalate (KHP) yielded the results in the following table. a. the average molar concentration of the base. Average molar concentration \( = \) \( \mathrm{M} \mathrm{NaOH} \) b. the standard deviation and the coefficient of variation for the data. Standard deviation \( =\quad \mathrm{M} \mathrm{NaOH} \) Coefficient of variation \( =\quad \% \) c. the spread of the data. Spread \( =\quad \mathrm{M} \mathrm{NaOH} \)
