xLof N2 GAS AT STP contains 3*1022molecules.
the number of molecules in ozone at STP will be
give the answer with complete explanation

No of molecules = No of moles x NA ( N- Avogadro Number)

No of moles = No of moleculesNA

                   =  3 × 10226.023 × 1023
                
                   =  0.4981 x 10-1  = 0.04981 moles

1 mole of any gas occupies 22.4 L at STP

so 0.04981 mole occupy = ?
                                        =  22.41 × 0.04981
                               
                                         =       1.115  L               

The volume of N2 at STP = 1.115 L
If the volume of Nitrogen and Ozone are equal,
22.4 L is occupied by 1 mole.
The no of moles of Ozone present in 1.115 L = ?
                                                     = 122.4 × 1.115

                                                    = 0.04981 moles
No of molecules = mole x NA

                          = 0.04981 x 6.023 x 1023

  ​                       = 3 x 1022 

No of molecules in ozone = 3 x 1022 

Thus both of them have same no of molecules
