At one time, benzene was obtained almost entirely from coal tar; however, since about 1950, these methods have been replaced by petroleum-based Sigma-Aldrich offers a number of Benzene products. C: Kinematic Viscosity Centistokes: Density kg / litre: Vapour Pressure kPa. What is the volume of 1.10 mol of benzene (C6H6) at 20.7 degrees C? (a) Calculate the densities of solutions containing \$20,40,60,\$ and 80 volume percent benzene. The surface tension of benzene at 20°C is 28.85 dyne/cm. You are given the density of benzene (0.879 g/mL) and the amount of benzene (0.950 mol). We are told density is 0.879 g/ml. Solution for A 25.0-mL sample of benzene at 20.4 °C was cooled to its melting point, 5.5 °C, and then frozen. Density of selected materials (~20 °C, 1 atm) material density (kg/m 3) material density (kg/m 3); acetone: 790 : kerosene: 810: acid, acetic (CH 3 COOH): 1,050 : lard: 919: acid, hydrochloric (HCl) Density of a material is the amount (usually in grams) of material divided by the volume (usually in mL) of the material. Density is a measure of the amount of mass contained in a unit of volume.The general trend is that most gases are less dense than liquids, which are in turn less dense than solids, but there are numerous exceptions. Benzene has a boiling point of 80.1 °C (176.2 °F) and a melting point of 5.5 °C (41.9 °F), and it is freely soluble in organic solvents, but only slightly soluble in water. No. Benzene is an organic chemical compound with the molecular formula C 6 H 6. Benzene weighs 0.87865 gram per cubic centimeter or 878.65 kilogram per cubic meter, i.e. Find the true mass of benzene when the mass weighed in air is 12. The molar volume of liquid benzene (density = 0.877g/ml-1) increases by a factor of 2750 as it vaporises at 20 ° C and that of liquid toluene (density = 0.867g mL-1) increases by a factor of 7720 at 20 ° C. A solution of benzene and toluene at 20 ° C has a vapour pressure of 46.0 torr. The density of liquid benzene, C6H6, is 0.879 g/cm3 at 15 °C. C6H6 is the molecular formula for Benzene. The table was taken from "Perry's Chemical Engineers' Handbook" by Robert H. Perry, Don Green, Seventh Edition.
