Homework Help: Chemistry colution prep question (quick)

  1. Oct 8, 2011 #1
    1. The problem statement, all variables and given/known data

    I have to dissolve phenylthiourea in a phosphate buffer solution. The final molarity of the phenylthiourea is 10^-5, but it says to dissolve it in ethanol. Does this mean that I have to dissolve my weight of phenylthiourea in a minimal amount of ethanol, then bring that to volume with the phosphate buffer?

    2. Relevant equations

    3. The attempt at a solution
