Answer:
In a cylindrical water tube of length 4 cm and
radius 6 mm, at t=0 s, the concentration of
mole
molecules of oxygen changes from 0.5
m3
mole
to 0.1
across the tube.
If the diffusion constant of oxygen inside water
is 8x 10-10 m2
find:
S
The number of mole of oxygen going from the
higher concentration to the lower concentration
every second
n =
v mole
