Abstract :This work is aimed to attract attention to monomer fraction density (MFD), the variable that has not yet taken its place in the theory of real gases. The work shows that this variable can be calculated for monocomponent real gases from experimental isothermal dependences of their density on pressure and can be used for calculations of Gibbs energy, entropy and clusters equilibrium constants in real gases. The MFD-based joint series expansions method for density and pressure is suggested as an alternative to virial expansions. This method corresponds to the chemical equilibrium theory and provides new non-obvious results.
