Consider a 50.0 g sample of CO2 in a 150 cm3 vessel at 373 K. Calculate the pressure of the sample using each of the following approaches: assuming perfect gas behavior (i.e, using the ideal gas law). using the virial equation. The second virial coefficient for CO2 at this temperature is B = -72.2 cm3/mol. [source: Atkins Phys. Chem, 11th ed.] assuming the behavior is described by the van der Waals equation of state, with a = 3.610 atm dm6...
