The experiment is about titration of vinegar with NaOH. Before I start titration, I need to calculate how much of vinegar I will want to be using. I think I might use 50ml of distilled water to mix vinegar and I am gonna drop 3drops of phenolphthalein as indicator.
Please help me how to calculate amount of vinegar that I need to use....

Please Please Please help me... :(

    Vinegar (you can look on the bottle to see) usually is about 5% acetic acid. Convert that 5% (some are 4%) to molarity, then start with enough vinegar to use approximately 40 mL of the NaOH. You can use mL vin x M vin = mL NaOH x M NaOH.
    Will this get you started?
