  1. Oct 6, 2008 #1
    1. The problem statement, all variables and given/known data

    suppose that for a 10 mL sample of Ba(OH)2 solution, the mass of the cubicle with precipitate is 17.539g and the mass of the empty cubicle is 17.410g. calculate the concentration of the Ba(OH)2 solution from this data.

    2. Relevant equations

    3. The attempt at a solution

    You can find the molar mass of Ba(OH)2 with the periodic table, the change in mass of the crucible is the mass of the Ba(OH)2, which means you can find the # of moles of Ba(OH)2 you got. And finally you know that concentration is mole per liter.
