a)Concentration of the solution

  • chemistry -

    What units do you want concn. The easy way is 23g/1.5L.
    You may want molarity. That will be
    mols NaOH = 23/molar mass NaOH.. Then
    M = mols/L solution.
    b. pOH = -log(NaOH)
    c. pH + pOH = pKw = 14. You know pOH and Kw, solve for pH.
