WebFrom the heat of vaporization, in calories per cubic centimeter of liquid, we can derive the cohesive energy density (c) by the following expression where: c=Cohesive energy density h=Heat of vaporization r=Gas constant t=Temperature vm=Molar volume WebToluene, C6H5-CH3, is a clear colorless liquid, highly flammable with a sweet, pungent aromatic odor. Toluene is less dense than water and is slightly soluble in water. Hence it floats on water . Toluene vapor is heavier than air. Toluene may be toxic by inhalation, ingestion or skin contact.
