Potassium hydrogen phthalate (abbreviated as KHP) has the molecular formula \( \mathrm{KHC}_{8} \mathrm{H}_{4} \mathrm{O}_{4} \) and a molar mass of \( 204.22 \mathrm{~g} / \mathrm{mol} \). KHP has one acidic hydrogen. A solid sample of KHP is dissolved in \( 39 \mathrm{~mL} \) of water and titrated to the equivalence point with \( 22.50 \mathrm{~mL} \) of a \( 0.1490 \mathrm{M} \) \( \mathrm{NaOH} \) solution. How many grams of KHP were used in the titration? Mass \( = \) \( g \)
