Is Oil More Dense Than Water

Oils are basically large hydrocarbon molecules of many times the molecular mass of water molecules so you might expect them to be denser.

Is oil more dense than water. Oil being less dense than water floats on it. Essential oils typically have a lower than water density and are on top of the aqueous phase. However at a bald physical level that is apparently very surprising. But water is a very seriously weird substance.

I believe mineral oil is less dense than water because water has a density of 1g ml while mineral oil has a density of about 0 8g ml. Had it been denser than water like iron it would have sunk. It means that if you take a cubic cm cc of oil its mass is much lesser than a cubic cm of water. The molecules that make up the oil are larger than those that that make up water so they cannot pack as tightly together as the water molecules can.

Oil is less dense because its particles aren t as close together weighing it down. Density is mass per unit volume. A pinene for example has a density of 0 858 g ml 1 8 cineole has a density of 0 922 g ml. Yes syrup is more dense than water because of the sugar and oil is less dense than water like all other oil.

They take up more space per unit area and are less dense. This can be verified by placing olive oil and water together and observing how olive oil stays on top of the water proving itself to be lessdense. Oil is more dense than alcohol but less dense than water. Clearly oil is less dense than water as it floats on the surface of any body of water.
