I have this task that I had to solve. I am going to translate it as good as I can from the original language:
The diffusion coefficient of Piroxicam in aqueous solution is 5,45*10-10 m2s-1 at 25 C. The Viscosity of water at 25 C and 37 C is respectively 8,91*10-4 Pa s and 6,92*10-4 Pa s
I used the following formulas in order to find the diffusion coefficient:
R=kT/6πηD and got 4,42*10-10 m
D=kT/6πηR and got 7,42*10-10 m2 s-1
However, once checking for my answer I saw that the last answer was correct but they also included this answer: 4,45*10-4 cm2 min-1
How did they achieve this answer? I hope someone can help me.
Thanks in advance!
