#### Abstract

In the statistical calculation of the thermodynamic properties of ideal gases the translational contribution is calculated from the Sackur-Tetrode equation, S = R1n (2π MkT)^{3/2} ÷ (h^{3} N^{5/2}) V + 5/2 R in which S is the entropy of one mole of a gas of molecular weight M, at absolute temperature T, and volume V expressed in cubic centimeters; k is Boltzmann's constant; h is Planck's constant; N is Avogadro's number; and R is the molal gas constant expressed in the same units as those desired for S, usually cal deg^{1} mole^{1}.
