The volume of 50 g of a substance is 20 cm3. If the density of water is 1 g cm−3, will the substance float or sink?
If the density of an object is more than the density of a liquid, then it sinks in the liquid. On the other hand, if the density of an object is less than the density of a liquid, then it floats on the surface of the liquid.
Here, density of the substance `="Mass of the substance"/"Volume of the substance"=50/20=2.5" g cm"^-1`
The density of the substance is more than the density of water (1 g cm−3). Hence, the substance will sink in water.
