Answer:

DAB = 1.921 E-5 m²/s

Explanation:

DAB = ((1 E-7 T∧(1.75))*((1/MA + 1/MB)∧(1/2)))/[ P*(∑vA)∧(1/3) + (∑vB)∧(1/3)]².......Fuller et All.

∴ ∑vA = 16.1 m³/Kg....from literature

∴ ∑vB = 16.6 m³/Kg....from literature

∴ T = 294 K

∴ P = 1 atm

∴ MA = 39.948  Kg/Kmol

∴ MB = 32 Kg/Kmol

⇒ DAB = ((2.087 E-3)*(0.2372))/[1*(25.766)]

⇒ DAB = 1.921 E-5 m²/s
