Homework Help: 2 fold dilution

  1. May 11, 2009 #1
    *** 2 fold dilution ***

    1. The problem statement, all variables and given/known data

    I have a mouthwash bottle with 0.05% of sodium fluoride (it says on the back)

    What i am tying to do is get 6 different concentrations? idk,

    I am helping my brother with an experiment: THere are 6 glasses with soda, and cookies. in there also is a a whole egg. I want to put different concentrations of the mouthwassh inside the 6 glases.

    the experiment is if different concentrations of mouthwash inside theglass with cookies soda and the egg, will make the egg dirtier or cleaner.

    ex( more mouthwash = more cleaner)

    so how do i make different concentrations?
