Suppose a student titrated vinegar, which is an acetic acid solution, of unknown strength with a sodium hydroxide solution according to the following equation. HC2H302 + NaOH + H2O + NaC H202 If 16.92 mL of 0.1506 M NaOH were required to titrate 5.00 mL of HC2H2O2. What is the percent (mass/volume) of the vinegar? The molar mass of acetic acid is 60.1 g/mol.
