what is the percentage of water in
Ba(OH)2 x 8H2O?

  • chemistry -

    You have 20 lbs fruit with 10 lbs being oranges and the others apples. What is the percent oranges.
    %oranges = (weight oranges/total weight)*100 = (10/20)*100 = 50%.
    Percent works the same way in chemistry.
    %H2O = (mass H2O/mass sample)*100 =
    (8*molar mass H2O/molar mass Ba(OH)2.8H2O)*100 = ??
    Note: The molar mass Ba(OH)2.8H2O is molar mass Ba(OH)2 plus molar mass 8H2O and not times 8H2O.
