My Notes Ask Your Teacher 7. 0/1 points I Previous Answers KatzPSEf1 20.P.065. 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? 2.159E11X Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully. yr Need Help? Read I Submit Answer Save Progress Practice Another Version

Explanation / Answer

x = distance = 50.9 m

D = diffusion constant = 2 x 10-9 m2/s

time taken is given as

t = x2/D

t = (50.9)2/(2 x 10-9 )

t = 1.3 x 1012 sec
