can you solve parts d and e

Calculate Z and V for ammonia at 320 K and 15 bar by the following equations: (a) The truncated virial equation (Eq. (3.38)] with the following values of virial coefficients: B = -208 cm3 .mol-1 C = 4378 cm mol 6. -2 (b) The truncated virial equation [Eq(3.36)], with a value of B from the generalized Pitzer correlation (Eqs. (3.58)-(3.62) (C) The Redlich/Kwong equation (d) The Soave/Redlich/Kwong equation (e) The Peng/Robinson equation
