3.34. Calculate Z and V for sulfur hexafluoride at 75 C and 15 bar by the following equa- tions: (a) The truncated vitial equation (Eq. (3.40)) with the following experimental values of virial coefficients B = -194 cm molt C = 15.300 cm mot- ) The truncated viral equation [E4. (3.38)], with a value of B from the generalized Pitzer correlation (Eq. (3.63). (c) The Redlich/Kwong equation. (d) The Soave/Redlich/Kwong equation. te) The Peng/Robinson equation. For sulfur hexafluoride, T = 318.7 K, P = 37.6 bar. Vi = 198 cm' moll and 0.286
