    1.3 * 10⁴ mL

    Explanation:

    A Pb-contaminated water sample contains 0.0012 %Pb by mass, that is, there are 0.0012 g of Pb in 100 g of solution. The mass of the sample that contains 150 mg (0.150 g) of Pb is:

    0.150 g Pb * (100 g sample/0.0012 g Pb) = 1.25 * 10⁴ g sample

    The density of the sample is 1.0 g/mL. The volume of the sample is:

    1.25 * 10⁴ g * (1 mL/1.0 g) = 1.3 * 10⁴ mL
