7. 0/1 points Previous Answers KatzPSEf1 20.P065 My Notes Ask Your Teache A lifeguard pours chlorine into a pool and assumes it will eventually diffuse throughout the pool. Assuming diffusion alone is acting and the diffusion constant of chlorine in water is 2 × 10-9 m2/s, how long would it take for the chlorine to diffuse from one end of the pool across the 50.9-m length to the other side? 1.3E12 X Your response differs significantly from the correct answer.

Explanation / Answer

Diffusion constant = 2*10^-9 m2/s

Length of pool= 50.9 m

Area of pool = 50.9*50.9 = 2590.81 m2

Time to take = area/diffusion constant

= 2590.81 m2 / 2*10^-9 m2/s

=( 1.295 x 10^12 s) x (1yr/31536000 s)

= 41077.023 yr = 4.1 x 10^4 yr
