Answer the following question with respect to Avogadro's law

Dear student ,
As per the Avogadro's law , under the same conditions of temp. and pressure if same volume of the gases are taken then their no. of moles are also same. 
Now the moles of the each gases =  Y /  6.02 x 1023 
Volume of each gases having same no. of molecules =  V L
(i) now the volume of Y molecules of Cl2  =  V l
(ii)   volume of 3Y molecules of SO2 =  3V L
(iii)  Now the given that ,
Mass of the Y molecules of O2  =  16 gm 
Now , 6.02 x 1023 molecules of O2  has 32 gm 
or 32 gm of O2 has 6.02 x 1023 molecules
so 16 gm of O2 has  3.01 x 1023 molecules  =  Y 
Now for the CO2  :
6.02 x 1023 molecules has the mass = 44 gm 
thus 3.01 x 1023 molecules of CO2  has = 22 gm 
Regards
