The OPAL equation-of-state tables and the MHD equation-of-state tables are utilized in the calculation of new standard solar models that also include helium diffusion. The structure of the models and their l = 0-100 p-mode oscillation spectra are compared. The p-mode frequencies of the standard solar model are dramatically and nearly identically affected by the inclusion of these detailed equation-of-state formulations. The sensitivities of the p-mode frequencies to other physical uncertainties, in particular the surface conditions, are also discussed.
