When constructing stellar models, the stellar opacity is normally described by the wavelength-independent Rosseland mean opacity. Three of the main sources that may contribute to the mean opacity are electron scattering, bound-free, and free-free opacity. Write down how each of these sources depends on the composition (X, Y, and/or Z) of the star. Then make an informed decision on how Ko will vary with X, Y, and/or Z for a star with M = 1 Mo and internal temperatures in the range of 10^6 - 10^7 K (see the Assignment 2 Canvas page for a phase diagram that may be helpful).
