Assume that the diffusion coefficient of glucose is 5.70 × 10−7 cm2/s. calculate the time it would take for a glucose molecule to diffuse 11.3 μm.

The diffusion coefficient of glucose is . Glucose molecule diffuse to , time for diffusion can be calculated as follows:

To calculate the time first convert x into cm

Also,

Thus,

and,

Putting the values,

Therefore, time taken for diffusion will be 1.12 s.

step-by-step explanation:

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
