    0.5ppm

    Explanation:

    Step 1:

    Data obtained from the question.

    Volume of water = 2500L

    Mas of Cu = 1.25 g

    Step 2:

    Determination of the concentration of Cu in g/L. This is illustrated below:

    Volume of water = 2500L

    Mas of Cu = 1.25 g

    Conc. of Cu In g/L = ?

    Conc. g/L = Mass / volume

    Conc. of Cu in g/L = 1.25/2500

    Conc. of Cu in g/L = 5x10^-4 g/L

    Step 3:

    Conversion of the concentration of Cu in g/L to ppm. This is illustrated below

    Recall:

    1g/L = 1000mg/L

    Therefore, 5x10^-4 g/L = 5x10^-4 x 1000 = 0.5mg/L

    Now, we know that 1mg/L is equal to 1ppm.

    Therefore, 0.5mg/L is equivalent to 0.5ppm
