I don't understand where the highlighted number came from to get to the correct answer

Conditions; oxygen is observed to be initially 10% supersaturated:
Temperature = 18 °C; salinity = 35%; density 1025 kg m-³; Oxygen conc. at
saturation (Table D.3) = 234.0 µmol kg-¹, = 239.85 mmol m-3; Oxygen concen-
tration measured in the bulk water 263.84 mmol m³; Wind speed, u, (at 10 m)
over the ocean = 7.4 m s¹ (about 14 knots); Schmidt number for O₂ at this
temperature (Table D.11) = 651
Calculation:
From Eq. (5.10), flux =
=
1.92u²
Scº.5
=
([G]₁ - [G]w)
=
= -98.86 mmolm¯²d-¹.
