From the question asked, it seems about Calculation for the compressibility factor,

Compressibility factor of gases is a thermodynamic property which is used to modify the ideal gas equation for real gases.

For Ideal gases, 
PV = nRT

For real gases, 
PV = ZnRT, (Z is the compressibility factor for the given gas)

The compressibility factor of a gas depends on the particular gas as well as temperature and pressure conditions.

Various equations of state can be used for calculation of compressibility factor of a gas as a function of temperature and pressure. Using different equations of state, various equations are derived for compressibility factor calculation. The constant parameters used in these equations are empirically determined for a gas.

Compressibility charts express compressibility factor values as a function of reduced temperature and reduced pressure.

Reduced temperature, Tr = T / Tc
Reduced pressure, Pr = P / Pc

where Tc and Pc are critical temperature and pressure values respectively.
