    The volume of water he dissolved the solute is 250 cubic centimeter.

    Explanation:

    Concentration = mass of solute in g / volume in dm^3

    The concentration of a solution is defined as the ratio of mass of solute in grams to the volume of water in dm^3.

    If concentration of a solution = 8 g/dm^3.

    mass of solute = 2 g.

    Volume of a water = 2 / 8 = 0.25 dm^3. (or) 250 cubic centimeter.
