Based on the mass relation derived under the assumption that for the almost ideally mixing meson nonets, the corrections deduced by the flavor-dependent quarkonia transition can be ignored, the mass of the isodoublet of the 2 S-1(0) nonet is predicted to be 1391.8 +/- 67.7 MeV. The quarkonia content of isoscalar states of the 2 S-1(0) nonet, i.e. eta(1295) and eta(1475), is given, and some predictions on the decays of the two isoscalar state are presented. These predictions can be tested in Beijing Electron Positron Collider/Bejing Spectrometers (BEPC/BES) with 58 million J/psi events in the near future.
