4. 1050 gram-moles of helium (Tc=5.19K and Pc=2.27 bar, Pitzer acentric factor =0.390 ) is contained in a 5 -liter vessel at 246.77C. Estimate the pressure in the cylinder using I. Ideal gas equation of state II. Virial equation of state III. Van der Waals equation of state IV. SRK equation of state V. Compressibility factor equation of state with the generalized compressibility chart VI. The percentage error is calculated using the ideal gas equation versus the virial, van der Waals, SRK, and compressibility factor equation of state equations
