A certain volume of hydrogen diffuses through a porous pot in 30seconds. Calculate the time taken for the same volume of HCL to diffuse under the same condition

1 answer

rate = volume/time. Let's just take a volume of 30 cc then rate H2 = 30/30 = 1 cc/sec
mm = molar mass
x = rate HCl
(rate H2/rate HCl) = sqrt (mm HCl/mm H2)
(1/x) = sqrt (36.5/2)
solve for x = 30 cc HCl/time HCl)
Then solve for time HCl.
