What is the molarity of 550.0 mL of KOH solution, that reacts completely with 675 mL of a 0.450 M CrCl3 solution?

    balance the equation:

    3KOH+ CrCl3>>3KCl + Cr(OH)3

    notice for each mole of CrCl3, you use three moles of KOH.

    moles of CrCl3=.450*.675
    moles of KOH=3*.450*.675
    molarity of KOH= moles KOH/.550
