How would set up a problem like this?

A mass of 20.0 g of NaOH is dissolved in water to form 5.0 dm^3 of solution. What is the molarity of the hydrogen ion concentration if the temperature is 25 degrees Celsius?

  • chemistry -

    M = #moles/dm^3
    moles = grams/molar mass
    Solve for moles.
    Substitute moles and dm^3 to find M. Then
    pOH = -log(OH^-) and solve for pOH.
    Then pOH + pH = 14 and solve for pH.
