Homework Help: Geometric Dilution/Series

  1. Dec 10, 2011 #1
    1. The problem statement, all variables and given/known data

    you are geometrically diluting/mixing 0.1 g of powder A with 100g of powder B, how many times do you have to mix the 2 together to finish the process?
    *each time you can only mix an equal portion of powder B to what you currently have mixed.


    3. The attempt at a solution

    So the first time you mix them it will be
    0.1 g + 0.1 g --> 2^0
    0.2 g + 0.2 g --> 2^1
    0.4 g + 0.4 g -->2^2???

    I don't know what to do from here?
