When can you use it?
The Ideal-gas equation may be used as a reasonable approximation of reality when Z0 lies between .98 and 1.02

Checking the Validity of an Ideal Gas Assumption
Look at the specific molar volume of the gas. The ideal gas equation is good to within about 1% if:

Generalized Correlations for Liquids
This correlation is most suitable for nonpolar and slightly polar fluids. For estimation of molar volumes of saturated liquids.

Generalized Correlations for Liquids Cont.
Lydersen, Greenkorn, and Hougen’s two-parameter correlation for liquid volumes.
is reduced density
is density at the critical point

Generalized Correlations for Liquids Cont.
Using a single known liquid volume:
V2 = required volume
V1 = known volume
= reduced densities from figure 3.16
