The solute acetone $($A$)$ is diffusing through a thin film of water $($B$)5mm$ thick at $298K.$ The concentration

of acetone at point $1$ at one boundary of the film is $10wt\%$ acetone, and the other boundary at point $2$

it is $5wt\%$ acetone. Assuming steady$-$state and one boundary impermeable to water, calculate the flux

of acetone.

Molecular weight of acetone $=58\frac{g}{m}ol,$ molecular weight of water $=18\frac{g}{m}ol$
