The volume of 50 g of a substance is 20 cm3. If the density of water is 1 g/cm3, will the substance float or sink?

The volume of 50 g of a substance is 20 cm3. If the density of water is 1 g/cm3, will the substance float or sink?

Answer:

A substance floats on water if its density is less than the density of water. A substance sinks in water if its density is more than the density of water.

Density of a substance > Density of water   (substance sinks in water)

Density of a substance < Density of water   (substance floats on water)

Given:
Volume   =   20 \large cm^{3}
Mass   =   50g
Density of the given substance   \large\bf \hspace{3pt} =\hspace{3pt} \frac{mass}{volume}

                                                     \large\bf = \frac{50g}{20cm^{3}}

                                                     \large\bf = 2.5 g/cm^{3}

Density of water \large\bf \hspace{2pt} = \hspace{2pt} 1g/cm^{3}

Here density of the given substance is more than the density of water. So the given substance will sink in water.
