Homework Help: Volume/Volume %, manipulating units

  1. Oct 4, 2008 #1
    I am trying to find % acetic acid by volume in vinegar.

    I have 8*10-4 mol/L of acetic acid in vinegar and 8*10-5 of acetic acid in the dilute sample of vinegar and water.

    I know that the volume/volume % is equal to the amounts of A divided by the total amounts of A and B. BUT that they also should be in mL, considering the density (the assumed density) of water, vinegar and acetic acid is 1.00g/mL.

    So I'm having trouble with finding out how to convert the mol/L into just mL. Also having trouble figuring out what A and A+B are. I am assuming A is the volume of acetic acid in vinegar and A+B is the volume of acetic acid in the dilute sample?

    mol/L can be converted into grams/L which can be converted into grams/100mL.
