(10 points) Real Gasses Ammonia vapor is compressed to 60bar and 105C. Use the SRK equation of state to determine the vapor mass density (g/L). For ammonia, Tc=405.5K,Pc=111.3atm, and =0.257. a. Determine Tr,a,b,m, and . b. Plot the pressure as a function of specific volume over a range of 0.055L/mol. Make sure to properly label the axes. Plot a sufficient number of points to get a smooth curve and use a logarithmic scale for the x-axis. You must use Excel to prepare your plot. Axes should be properly labelled, and the plot must have a title. c. Determine the specific volume of ammonia vapor at 60 bar and 105C(L/mol). d. Determine the vapor mass density (g/L)
