Then you are overlooking the gravity of the atmosphere. The gravity of the shell is zero inside the shell, but even if the 1.25 bar of breathemix is magically prevented from self-gravitating towards the centre its mass is about 1.25 × 0.029 kg/mol × 44.5 mol/m^3 × 4π/3 × (3.65 × 10^13 m)^3 = 3.29 × 10^41 kg = 1.6 × 10^11 solar masses. Assuming standard temperature and pressure throughout.
Surface gravity of the uniform sphere of breathemix would be about 16.5 × 10^4 m/s^2 = 1 682 gees.
