Hi,

This question is in reference to my lab: Determination of Acetic Acid (using vinegar as a titration). 5ml of vinegar was used in the titration and 1M NaOH.

I need to know how to calculate the data for my “Vinegar Sample 1” . I have 6 question marks that I am not sure how to calculate. After you show me how to do it, I can calculate my other samples.

Thank you kindly!

CH3CO2H + NaOH → NaCH3CO2 + H2O

Mass of Vinegar: 5.09

Volume of Vinegar (Density = 1.005 g/mL): ?

Initial NaOH volume in syringe: 10ml

Final NaOH volume in syringe: 5.5ml

Volume of NaOH Delivered: 4.5ml

Moles of NaOH Delivered: 0.0045 moles?

Moles of Acetic Acid in Sample: ?

Mass of Acetic Acid in Sample: ?

Calculated Molarity of Acetic Acid in the sampled vinegar: ?

Calculated Percent Mass of Acetic Acid in sampled vinegar: ?
