2). Calculate the compositions and densities of the equilibrium liquid and gas of the mixture given below at 160F and 2000 psia. Use binary interaction coefficients of 0.021 for methane-n-butane, 0.032 for methane- n-decane, and 0.0 for n-butane- n-decane. The pre-specified tolerance is for 0.098 . Note: The first trial must be done manually; then use your own coded program to perform the necessary iterations. Compare your answer with experimental results shown below
