Compressibility Factor Calculator

Posted by Dinesh on

Online Gas Laws Calculator to calculate compressibility factor Z for non ideal gases. The compressibility factor Z is the ratio of the molar volume of an ideal gas of same number moles and the molar volume of a real gas at the same pressure and temperature. This physical chemistry tool predicts or computes the compressibility factor Z or gas deviation factor for non ideal gases.

Compressibility Factor Z for non Ideal Gases Calculation

Formula:

Z = (P × V) / (n × R × T)

where,
  • P = Pressure
  • V = Volume
  • n = number of Moles
  • R = Universal Gas Constant ( 8.3144598 J K?1?mol?1)
  • T = Temperature
  • Z = Compressibility factor
