Question

What is density of a substance with a mass of 157 g and a volume of 412 cm3. Can this substance float on water?

Answer 1

yes it can float on water because it's density is less than watter

Answer 2

density of substance
$= \frac{mass}{volume}$
$= \frac{157}{412}$
=0.381 g/cm^3
density of water is 1g/cm^3
so the substance would float as it has less density.
