The solute HCl (A) is diffusing through a thin film of water (B) 2.0 mm thick at 283K. The concentration of HCl at point 1 at one boundary of the film is 12.0 wt % HCl (density 1 = 1060.7 kg/m³) and the other boundary at point 2 it is 6.0 wt % HCl (density 2 = 1030.3 kg/m³). The diffusion coefficient of HCl in water is 2.5 × 10^-9 m²/s. Assuming steady state and one boundary impermeable to water, calculate the flux of HCl in kg.mol/s.m².
