a. (5 x 2 points) Show the chemical formula and the structural formula of ortho-xylene (1,2- dimethylbenezene). b. (5 points) Calculate the aromaticity of ortho-xylene. c. (10 points) Using the figure of Yarborough on aromaticity (on lecture slides), calculate the specific gravity for a carbon number of 15 and an aromaticity of 30. What is the API gravity for that fluid using Equation 10.2 of Dandekar (page 277)? d. (5 points) Table 10.2 of Dandekar shows a cutoff API of 40° for "Black oils" and "Volatile oils." What is the mass density (Ib/ft³) for an oil with 40°API? e. (5 points) (Mass) density of a fluid depends on temperature, pressure, and composition. What are the temperature and pressure used for the definition of specific gravity (yo) based on Section 10.4.2 of Dandekar? f. (10 points) Again, density of a fluid depends on temperature, pressure, and composition. Part d above indicated that black oil is denser than volatile oil at the standard conditions. Explain why, by discussing chemical composition or molar distribution for these types of fluids.
