Both containers have the same number of molecules.
Reason: At the same temperature and pressure, equal gas volumes contain the same number of molecules (Avogadro's law). The specific number 6.022×10^23 would be one mole occupying 22.4 L only at 0°C (STP). At 25°C, 22.4 L corresponds to about 0.916 mol (≈5.5×10^23 molecules), but both containers still contain that same amount.
