Homework Help: What is the number of moles of OH- in 0.3 L OF 0.005 M Ba(OH)- ?

  1. Oct 30, 2012 #1
    1. The problem statement, all variables and given/known data

    *0.3 L OF 0.005 M Ba(OH)-

    What is the number of moles of OH- in 0.3 L OF 0.005 M Ba(OH)- ?


    2. The attempt at a solution

    In 1 mol ba(oh)2--------> 2 mol OH-
    so

    In 0.005 M ba(oh)2 ----------------> 2 x 0.005 M OH-

    I know I am doing something wrong.

    please help

    thanks in advance.

    You are asked about BaOH-, but you are calculating for Ba(OH)2?
