(2) C mass percent of acetic acid in the vinegar sample. You may want to brealk the calculation down to the following steps: Using the volume and molarity of NaOH, find the number of moles of NaOH that were used in this titration. Use this to get the number of moles of acetic acid in the vinegar sample that was titrated. Convert moles of acetic acid to grams of acetic acid for the vinegar sample that was titrated. To do this, you will need acetic acid's molar mass. (Note: HOAc is NOT the formula, the actual formula is HC2H302.) After converting grams to moles, you now have the mass of acetic acid in the vinegar sample. o Now find the mass of the entire vinegar sample that was titrated. You may do this by assuming that the density of the vinegar solution is 1.02 g/mL Finally, find the percent acetic acid in the vinegar sample. .
