The diffusion of oxygen (o2) through living tissue is often first approximated as the diffusion of
dissolved o2 in liquid water. estimate the diffusion of o2 in water by the wilke-chang correlation
at 37℃.

Explanation:

We assume that is represented by A and is represented by B respectively.

According to Wilke Chang equation as follows.

where,   T = absolute temperature = (273 + 37)K = 310 K

        = an association parameter for solvent water = 2.26

    = Molecular weight of water = 18 g/mol

    = viscosity of water (in centipoise) = 0.62 centipoise

    = the molar volume of oxygen = 25.6

Hence, putting the given values into the above formula as follows.

                       =

                       =

Thus, we can conclude that the diffusion of in water by the Wilke-Chang correlation  at .

under a microscope, cancer cells may look very different from normal cells. they often have different sizes and some may be larger than normal while others are smaller. cancer cells are often abnormally shaped and the control centre of the cell (the nucleus) may have an abnormal appearance.
