"WebThe density of a liquid is a measure of how heavy it is for the amount measured. If you weigh equal amounts or volumes of two different liquids, the liquid that weighs more is more dense. If a liquid that is less dense than water is gently added to the surface of the water, it will float on the water. " - Density sciencedirect
