Calculate the accurate answer of the following problem

Problem- Calculate the entropy of the majority isotopic form of carbon monoxide gas ¹²C¹⁶O using the Sackur-Tetrode equation at room temperature and standard pressure. Derive the explicit temperature dependence of the entropy for the carbon monoxide isotope. Potentially helpful information: equilibrium bond length is 112.83 pm, fundamental vibrational mode has 2169.81 cm^-1.

I want experts assist to determine the entropy of the majority isotopic.
