• [Display omitted] •We present an explicit representation of molar entropy for gaseous substances.•Molar entropies of six gaseous substances are excellently predicted.•Present calculation scheme is useful to calculate molar entropy for other gaseous substances. We present an explicit representation of molar entropy for gaseous substances. Fortunately, through comparison of theoretical and experimental results, we discover that the molar entropies can be successfully predicted by applying experimental values of only four molecular constants for the carbon monoxide, hydrogen chloride, hydrogen fluoride, deuterium fluoride, gaseous boron monobromide, and nitrogen monoxide. The present entropy calculation scheme provides opportunities for predicting successfully entropy values of other gaseous substances with no use of a large number of experimental spectroscopy data.
