Question

The time required for the diffusion of 30 cc of ozone through a porous was as same as that for diffusion of 25cc chlorine gas under same condition. Determine the molecular mass and molecular formula of ozone.​

Answer 1

Answer: mol. mass of Ozone = 49.30g/mol

Molecular formula= O3

Explanation:

Using Graham's law of diffusion

(30cc/t)/(25cc)/t

=[ (Mchlorine)/(Mozone)]^1/2

Or, 35.5×2/Mozone = 36/25

Mozone = 71×25/36= 49.30 g/mol

Molecular formula is O3
