Calculate the diffusion coefficient of acetic acid (C2H402) in a solvent mixture consisting of 20 mol% Butane (C4HIJ and 80 mol% Heptane (C7H16) in cm2/s) at 303 K. The viscosity of the mixture is 1.35 cP, the association factor for butane and heptane 1, mole scales will be taken as 58.12 for butane, 100.21 for heptane, 60.1 g/gmol for acetic acid and 14.8 for C, 3.7 for H, 12 cm3/g.mol for O as an additive volume. .
