What is the Molarity of 70% TBHP?

  1. Aug 13, 2012 #1
    1. The problem statement, all variables and given/known data
    What is the Molarity of 70% TBHP?


    2. Relevant equations
    Given: d=.937g/ml, FW=90.12g , w/w%?


    3. The attempt at a solution
    1000mL x (0.937g/mL) x (1mol/90.12g) = 10.4M

    That is what I got but idk what to do with the 70% or that w/w%
    or is that right the way I did it?

    "Molarity of 70%" means .7 times one molarity. Do you know what a one molarity solution would be?

    So this is what I came up with now:

    1000mL x (0.937g/mL) x (.7) x (1mol/90.12g) = 7.28mol/L

    Is this correct now?

    If they are asking the molarity and they have given you density, then it is definitely w/w%

    No, in this context it means molarity of 70% solution of TBHP, 70% being most likely w/w.
