(2) Liquid toluene (C6H-CH3) was stored at 6.4°C in an open top 20-cm-diameter cylindrical container. The vapor pressure of toluene at 6.4°C is 10 mm Hg. A gentle stream of fresh air at 6.4°C and 101.3 kPa was allowed to flow over the open end of the container. The rate of evaporation of toluene into air was measured to be 60 g/day. Estimate the concentration of toluene (in g/m³) at exactly 10 mm above the liquid surface. The diffusion coefficient of toluene in air at 25°C is DAB = 0.084 x 104 m²/s.

(2) Liquid toluene (C6H5CH3) was stored at 6.4°C in an open top 20-cm-diameter cylindrical container. The vapor pressure of toluene at 6.4°℃ is 10 mm Hg. A gentle stream of fresh air at 6.4°℃ and 101.3 kPa was allowed to flow over the open end of the container. The rate of evaporation of toluene into air was measured to be 60 g/day. Estimate the concentration of toluene (in g/m³) at exactly 10 mm above the liquid surface. The diffusion coefficient of toluene in air at 25°C is DAB = 0.084 x 10-4 m²/s.
