A formula calls for 0.6 mL of a coloring solution. Using a 10-mL graduate calibrated from 2 to 10 mL in 1-mL units, how could you obtain the desired quantity of the coloring solution by the aliquot method? Use water as the diluent.

    let us add 2.4 mL of water in 0.6 ml of coloring solution

    total volume of solution = 2.4 + 0.6 = 3 mL

    therefore,

    0.6 mL of coloring solution now includes = 2.4ml of water

    or

    1 mL of coloring solution includes = 4mL of water

    Hence

    measure 3 mL of coloring solution with water that is formed

    therefore, this 3 mL will contain 0.6 mL of coloring solution

    Step-by-step explanation:

    Given:

    formula calls for 0.6 mL of a coloring solution

    10-mL graduate calibrated from 2 to 10 mL in 1-mL units

    Now,

    We want to use an aliquot technique to measure 0.6 ml of coloring solution.

    Because the calibrated graduate is used to measure 2ml to 10ml with 1ml as unit measure

    let us add 2.4 mL of water in 0.6 ml of coloring solution

    total volume of solution = 2.4 + 0.6 = 3 mL

    therefore,

    0.6 mL of coloring solution now includes = 2.4ml of water

    or

    1 mL of coloring solution includes = 4mL of water

    Hence

    measure 3 mL of coloring solution with water that is formed

    therefore, this 3 mL will contain 0.6 mL of coloring solution
