Question: PLEASE i have NO IDEA what to do on this TITRATION lab experiment question? i would appreciate some help ?

I did an experiment and found that the mean concentration (M) of HC2H3O2 (acetic acid) is 838. I also initially had the molarity of NaOH to be 0.25, and the volume of NaOH to be 34 mL.

they are asking me this:

the manufacturer of the vinegar used in this experiment claims that the vinegar contains 5% acetic acid by weight. Use your results and a density of 1.0 g/mL to investigate this claim.

thank u
oops, i meant the acetic acid’s molarity was 8.38 M

Answer: Wow, 838 M acetic acid? Are you sure you didn’t do something wrong? The most concentrated I’ve used was 15-20 M acetic acid.

I would say that the manufacturer of your vinegar is trying to kill you if they wanted to sell you 838 M acetic acid, or you got a really good deal.
