An object of mass 10.0 kg and volume 1000 ml and density 10 g/ml sinks in water who’s density is 1.0 g/ml. what is the mass of the water which has been displaced in kilograms

1000 grams or 1 kg

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.
