Abstract: The statistical weight of non-ideal gas is its most important characteristic of the underlying statistical theory of the macrosystem. In this paper the method of calculating the statistical weight of a non-ideal gas based on entropy of the critical state is proposed. Some non-ideal gases corresponding several well-known semi-empirical two-parameter equation of state are considered.

Keywords: semi-empirical two-parameter equation of state, non-ideal gas, critical state, entropy, statistical weight.
