His claim is false if you have done experiment correct and uses correct molarity and volume for NaOH and acetic acid.
This is because, we found that manufacturer vinegar has molarity of 0.833 M where you found 0.127 M be experiment

need it right now, please help me??
PROCEDURE PART I: DILUTING THE VINEGAR SOLUTION The vinegar solution must be diluted by a factor of 5 to be suitable for titration. 1. Obtain - 20 ml of the stock vinegar solution from the fume hood. 2. Using the 10-ml. pipet, pipet" 10 mL of the stock solution to a 50-ml volumetric flask. 3. Fill the volumetric flask to the calibration line with distilled water. Be sure not to go over...
the
concentration is .1000 M for NaOH. you cN disregard the second
column. but there is no further information.
equivalence point is 22.95. i dont have mL NaOH
this is all i have
