Question

492. A silent electric discharge was passed through 100 mL of air when 95 mL of
ozonised air was formed. The ozonised air took 48.7 seconds to diffuse through a
very small hole. If 100 mL of air diffused through the same hole under the identical
conditions, it took 50 seconds. Find the molecular weight of ozone assuming air
to contain 79% N, and 21% 0,-

[Hint: Composition of 95 mL of ozonised air is N, 79 mL, 0,10 mL and O, 6 mL.]​

Answer 1

Explanation:

ozonised air was formed. The ozonised air took 48.7 seconds to diffuse through a

very small hole. If 100 mL of air diffused through the same hole under the identical

conditions, it took 50 seconds. Find the molecular weight of ozone assuming air
