Calculate the molar volume of Ammonia by using Van der Waals equation of state (Eq. given below). Given that Temperature (T) = 400 K; Pressure (P)=12 MPa; Tc = 406.5 K; Pc = 11.27 MPa; and R = 8.134 cm MPa (mol K). Use MS excel solver function. (P+ 2)(V-b= (V-b)= RT RT a= 641 PC c b= RT 8PC Problem-2
