    Answer:

    Volume displaced by ducky = 75 mL = 7.5 x 10⁻⁵ m³

    Mass displaced by the ducky = 7.5 x 10⁻² kg = 75 grams

    Explanation:

    The ducky will displace the volume of the water equal to its own volume.

    Volume displaced by ducky = 75 mL = 7.5 x 10⁻⁵ m³

    And the mass displaced by ducky will be equal to:

    Mass displaced by the ducky = (Density of Water)(Volume displaced by ducky)

    Mass displaced by the ducky = (1000 kg/m³)(7.5 x 10⁻⁵ m³)

    Mass displaced by the ducky = 7.5 x 10⁻² kg = 75 grams
