Compressibility Factor, Z, for non Ideal Gases Calculator
P=Pressure, V=Volume, n=number of Moles, R=Universal Gas Constant, T=Temperature, Z=Compressibility factor
This online chemistry calculator may be used to compute the compressibility factor Z. Real gases do not follow the Ideal Gas equation. So, PV/nRT is not equal to 1. If we consider V to be the volume of a real gas then compressibility factor Z may be represented as V/(nRT/P). The denominator (nRT/P) can be viewed as volume of an ideal gas of n moles at temperature T and at pressure P. Thus compressibility factor is simply the ratio of the molar volume of a real gas and the molar volume of an ideal gas of same number moles and at the same temperature and pressure.
