Calculate Z and V for ethane at 50C and 15 bar by the following equations:
(a) The truncated virial equation [Z = PV/RT = 1 + B/V + C/V^2] with the following experimental values of virial coefficients:
B = -156.7 cm^3 mol^-1 C = 9650 cm^6 mol^-1
(b) The truncated virial equation [Z = PV/RT = 1 + BP/RT], with a value of B from the generalized Pitzer correlation [B = B^0 + wB^1].
(c) The Redlich/Kwong equation.
(d) The Soave/Redlich/Kwong equation.
(e) The Peng/Robinson equation.
