2 Problem 2 (25 points) 100 moles of a hydrocarbon mixture having the total composition of the mixture labeled 1 in Figure 1 is confined in a vessel maintained at a pressure of 500 psia and a temperature of 160 ° F. a. Calculate the moles of liquid in the vessel if any. Method 1. Apply the Inverse Lever Rule by measuring the lengths of the tie lines. n = 100 moles 12 23 2.7 0.3971 6.8 L L n L cm n n L cm = = = = * 100*0.3971 39.71 L L n n n moles = = = of liquid. Method 2. Apply the Inverse Lever Rule by using the formula on the data sheet. zy L i i L i i xy L n z y n n x y L - = = = - From the ternary diagram, we get 1 2 3 0.50 0.15 0.35 z z z = , 1 2 3 0.13 0.17 0.70 x x x = , 1 2 3 0.74 0.14
