Mineral oil is a hydrocarbon, meaning it contains nothing except carbon and hydrogen, with each molecule typically containing somewhere between 15 and 40 carbon atoms It typically has a density of about 08 g/mL (meaning 1 millileter of mineral oil would weigh 08 grams) Mineral oil is not soluble in water: If the two are mixed, they will form separate phases, with the mineral oil on top
