Does oil have more density than water?

Molecules of oil—carbon and hydrogen atoms bonded together—in the liquid phase. Oil is more dense than alcohol, but less dense than 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. read more

Oil is less dense than 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. They take up more space per unit area and are less dense. read more

Oil is composed of long chain hydrocarbon molecules so you would think it is more dense than water in that sense, but water is a polar molecule and will form hydrogen bonding with surrounding water molecules and hence, will be more closely packed giving a greater density since p=m/V. read more
