Title: molarity
Post by: Sambo on July 07, 2010, 03:47:52 PM

Calculate the molarity of acetic acid in a vinegar sample, knowing that 5.00 mL of vinegar requires 43.50 mL of 0.105 M NaOH to just reach the phenolphthalein endpoint in a titration. I m having trouble with this. Thanks!

Some tips: number of moles =  Molarity*volume
and writing the following equation could be useful:
CH3COOH + NaOH = ??
