Hi guys, I'm stuck on another question. Please if you can show me the steps. This question is puzzling me on account of the dilution.
Q: To analyse a sample of vinegar for its acetic content, a student began by accurately diluting a 20.00 mL sample of the vinegar to 250.00mL in a volumetric flask. THe student then placed 20.00 mL samples of this diluted vinegar in conical flasks and titrated them against a 0.05 mol L sln of sodium hydroxide. The average titre obtained was 21.52 mL.
Assuming that acetic acid is the only acid present in the vinegar, calculate the concentration of the acetic acid in the vinegar in grams per litre.
Also what does "titrated against mean"?
