  1. 19% is .2722 as concentrated as 69.8%, the volume has increased by a factor of 1/.2722 = 3.6737

    So, 183.68ml of 19% acid can be made.

    I do not still understand how to get 19% is .2722 ,

    the right answer is 183.68ml

  3. 19/69.8 = .2722

    19% is not .2722
    19% is .2722 of 69.8%

    Think about it. If you double the volume, the concentration is halved.

    Or, if you cut the concentration by a factor of 3, that means the volume has tripled.

    Here, you have cut the concentration by a factor of 3.6737, so that means the volume has grown by that factor.
