can you please solve and explian echa step A flexible polymer film $0\mathrm{.}051$ cm thick with an area of $85\mathrm{.}6$ cm$2$ is made into a bag,

filled with distilled water, and hung in an oven at $35$C and $75\%$ humidity. The bag is

weighed over time, giving the data in the table below.A flexible polymer film $0\mathrm{.}051cm$ thick with an area of $85\mathrm{.}6c{m}^2$ is made into a bag.

filled with distilled water, and hung in an oven at $35C$ and $75\%$ humidity. The bag is

weighed over time, giving the data in the table below.

If the rate of mass transfer across the film is described by the equation:

$m^{}=\frac{DH}{L}A[C_0-C_L]$

where $m$ is the rate of mass transfer across the film $(k\frac{g}{s}),DH$ is the film permeability

$(\frac{m^2}{s}),L$ is the thickness of the film $(m),A$ is the film surface area $(m^2),$ and $C$

represents concentration of the solute at a point outside in the film $(mo\frac{l}{m^3})$

$($ii$)$ What is the permeability $($DH$)$ of the polymer film?
