Benzene is diffusing through a slab of air 1 cm thick at 25ºC and 2 atm. The partial pressure of benzene is 50 mmHg at the left of the slab and 10 mmHg at the right of the slab. The mass diffusivity of benzene through air at 25ºC and 2 atm is 0.044 cm²/s. What is the mass flux of benzene (gmol/cm²-s) through a slab of air 1 cm thick? A. 9.47 E-8 B. 12. 38 E-8 C. 6.38 E-8 D. 5.38 E-8 Ans: A
