Standard Entropy in Statistical Thermodynamics Formulas

Standard Entropy (S°) is the absolute entropy of a pure material at 25°C (298 K) and 1 atm pressure. And is denoted by S°_m. Standard Entropy is usually measured using the Joule per Kelvin for Entropy. Note that the value of Standard Entropy is always negative.
