The volume of 50g of a substance is `20cm^(3)`. If the density of water is `1gcm^(-3)`, will the substances float or sink?

Answer

The substance will sink in water.

Explanation

Here mass =50g, volume `=20cm^(3)`
Density the substancxe `=("Mass")/("Volume")`
`=(50g)/(20cm^(-3))`
`=2.5 g cm^(-3)`
Density of water `=1g cm^(-3)`
The density of the substance is greater than that of water.
So, the substance will sink in water.
NOTE: The density can be found in `kgm^(-3)`. The density of water is `1000kgm^(-3)`
