Abstract Estimation of thermodynamic properties of gas mixtures using modified Benedict-Webb-Rubin equation by means of the Lee-Kesler method has known advantages over other methods. Mixture parameters, such as specific heat, enthalpy, entropy are estimated by summation of values of these parameters at ideal gas condition and corrections. Analytic dependences for enthalpy and entropy corrections are known. The specific heat at constant pressure correction relates to enthalpy correction by differential dependence, therefore it requires to use numerical methods to evaluate the specific heat correction. Computational formula for the specific heat at constant pressure correction has been obtained by solving this differential equation. Comparison between values of gas mixture basic thermodynamic parameters estimated using obtained formula and values estimated by other methods showed acceptable agreement for engineering computations.
