### Density of Ethanol - ScienceStruck

Density is defined as the mass per unit of volume. It basically depends on how closely the atoms are spaced in a particular object or liquid. If the object floats on water, it means the density of the object is less than the density of water, and if the object sinks, it means that its density is more than that of water.
