Water vapor diffuses through a stagnant air film of thickness $\delta = 2.0\text{ mm}$ over a wet food surface. The molecular diffusivity of water vapor in air is $D_{AB} = 2.5 \times 10^{-5}\text{ m}^2\text{/s}$. The partial pressure difference of water vapor across the film is $\Delta p = 2000\text{ Pa}$. Gas constant $R = 8314\text{ J/(kmol}\cdot\text{K)}$ and temperature $T = 300\text{ K}$. Using Fick's first law $N_A = \frac{D_{AB} \Delta p}{R T \delta}$, the molar flux $N_A$ in $\text{mol/(m}^2\cdot\text{s)}$ is ________ $\times 10^{-2}$ (round off to 2 decimal places).
