Answer:
1000 grams or 1 kg
Step-by-step explanation:
All that matters for this question is the volume of the object (1000 mL) and that the density of the object is more than the density of water.
Since the density of water is 1 gm/ mL and 1000 mL have been displaced, the answer is 1000 grams or 1 kg. You can actually calculate this from a formula.
density = mass / volume
density = 1 gram/ml
Volume = 1000 mL
mass = ?
mass = volume * density.
mass = 1000 mL * 1 gram / mL
mass = 1000 grams
Notice how you are focusing on the volume of the object and the mass of the water.
