HowwillyoudeterminetheatomicityofgasesusingAvogadro'shypothesis ?

Answer»

Solution :TheAtomicityof anelementcan bederivedusingAvogadro'shypothesis. LETUS considerthefollowingequation

Accordingto Avogadro'slaw , 1volumeof anygasoccup'n'numberof molecules.

ifn=1 then

(i )1 moleculeof hydrogenchloridegasismadeupof `1//2`moleculesofhydrogenand`(1)/(2)`Moleculeof chlorine
(ii)But1 moleculeof hydrogenchloridecontainsoneatomofhydrogenand 1 atomofchlorine
(III )Hence`(1)/(2) `moleculeof hydrogen =1 atomof hydrogen
(IV )OR1 molecule ofhydrogen=2 atoms ofhydrogen
(V )SO theatommicityofhydrogenis2 , andmolecularformulais `H_(2) ` similarly ,
`(1)/(2) ` Molecule ofclorine=1atomofchlorine1 moleculeofchlorine =2atomsofchlorineso theatomicityof chlorineis 2 ,and itsmolecularformulais `Cl_(2)`.
