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
Step-by-step 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
