How long does it take oxygen to diffuse a distance of 1 mm in water at room temperature? how long does it take oxygen to diffuse a distance of 1 mm in water at room temperature?
a. 170 s
b. 0.30 s
c. 0.03 s
d. 10 s

option A

Explanation:

given,

travel distance = 1 mm

diffusion constant for the  molecule  of oxygen in water = 1 x 10⁻⁹ m²/s

we know that

t is the time taken for diffusion

x = 1 mm = 10⁻³ m

D is the diffusion

        t = 500 s

so, the option to the answer is 170 s

the correct answer is option A
