A neutralization titration was performed to determine the benzoic acid (C6H5COOH) in a 500 mL sample. In order to prepare the titrant, 5 grams of NaOH was weighed and dissolved in 1 L of distilled water. 10 mL of the sample was titrated with the NaOH solution after adding an appropriate indicator to the erlenmeyer. Four trials were done and 2.5 mL, 2.7 mL, 2.6 mL and 2.4 mL of NaOH were consumed. What is the mass of benzoic acid as gram in the sample. (C:12 g/mol, H:1 g/mol, O:16 g/mol, Na: 23 g/mol)
